DAC1653Q/DAC1658Q

Quad 16-bit DAC: 10 Gbps JESD204B interface:

x2, x4 and x8 interpolating

Advance data sheet

Revision 2.3.1

1. GENERAL DESCRIPTION

DAC1653Q and DAC1658Q are high-speed, high-performance 16-bit quad channel Digital-to-Analog Converters (DACs).

The devices provide sample rates up to 2 Gsps with selectable 2, 4 and 8 interpolation filters optimized for multi-carrier

and broadband wireless transmitters.

When both devices are referred to in this data sheet, the following convention will be used: DAC165xQ.

The DAC165xQ integrates a JEDEC JESD204B compatible high-speed serial input data interface running up to 10 Gbps

over eight differential lanes. It offers numerous advantages over traditional parallel digital interfaces:

•Easier Printed-Circuit Board (PCB) layout

•Lower radiated noise

•Lower pin count

•Self-synchronous link

•Skew compensation

•Deterministic latency

•Multiple Device Synchronization (MDS); JESD204B subclass 1 compatible

•Harmonic clocking support

•Assured FPGA interoperability

There are two versions of the DAC165xQ:

•Low common-mode output voltage (part identification DAC1653Q)

•High common-mode output voltage (part identification DAC1658Q)

Two optional on-chip digital modulator converts the complex I/Q patterns from baseband to IF. The mixer frequency is set

by writing to the Serial Peripheral Interface (SPI) control registers associated with the on-chip 40-bit Numerically Controlled

Oscillator (NCO). This accurately places the IF carrier in the frequency domain. The 13-bit phase adjustment feature, the

12-bit digital gain and the 16-bit digital offset enable full control of the analog output signals.

The DAC165xQ is fully compatible with device subclass 1 of the JEDEC JESD204B standard, guaranteeing deterministic

and repeatable interface latency using the differential SYSREF signal.

Multiple Device Synchronization (MDS) enables multiple DAC channels to be sample synchronous and phase coherent to

within one DAC clock period. MDS is ideal for LTE and LTE-A MIMO transceiver applications.

The DAC165xQ includes a very low noise bypass-able integrated Phase-Locked Loop (PLL). This PLL is fully integrated

and does not need any external passive components. The device also supports harmonic clocking. Both features are useful

to reduce system-level clock synthesis and distribution challenges.

The internal regulator adjusts the full-scale output current between 10 mA and 30 mA.

The device is available in a HLA72 package (10 mm  10 mm).

11. APPLICATION INFORMATION

11.1 General description

The DAC165xQ is a quad 16-bit DAC operating up to 2 Gsps. A maximum input data rate up to 1000 Msps is supported to

enable more capability for wideband and multicarrier systems. The incorporated quadrature modulator and 40-bit

Numerically Controlled Oscillators (NCOs) simplifies the frequency selection of the system. This is also possible because of

the 2, 4 or 8 interpolation filters which remove undesired images.

The DAC165xQ embeds four DAC channels (A, B, C and D) that can be configured as a Single Link Quad (SLQ) in which

all four DACs are synchronized together or as two Dual Link Quad (DLQ) in which the two dual DACs (A/B and C/D) are

synchronized independently. The two NCOs are linked to the A/B and the C/D dual DACs, respectively. Regarding the

quad/dual mode used, the eight JESD204B lanes are configured as one single link configuration JESD204 link (one SYNC

signal for a specified number of lanes), or dual link configuration JESD204B links (two SYNC signals associated with a

specified number of lanes).

The DAC165xQ supports the following JESD204B key features:

•10-bit/8-bit decoding

•Code group synchronization

•Initial Lane Alignment (ILA)

•1 + x14 + x15 scrambling polynomial

•Character replacement

•TX/RX synchronization management via SYNC synchronization signals

•Multiple Converter Device Alignment-Multiple Lanes (MCDA-ML) device (subclass 1 compatible)

•Independent Link Synchronization support

•Deterministic latency

•Multiple Device Synchronization (MDS); JESD204B subclass 1 compatible

•Harmonic clocking support

•Number L of serial lanes: 1, 2, 4 or 8 (see LMF-S configuration)

•Number M of data converters: 1,2 or 4 (see LMF-S configuration)

•Number F of octets per frame: 1, 2, 4 (see LMF-S configuration)

•Number S of samples per frame: 1, 2 (see LMF-S configuration)

•Embedded test pattern (PRBS31, PRBS23, PRBS15, PRBS7, JTSPAT, STLTP)

The DAC165xQ can be interfaced with any logic device that features high-speed SERializer/DESerializer (SERDES)

functionality. This macro is now widely available in Field-Programmable Gate Array (FPGA) of different vendors.

Standalone SERDES ICs can also be used.

The DAC165xQ includes polarity swapping for each of the lanes and additionally offers lane swapping to enhance the

intrinsic board layout simplification of the JESD204B standard. Within each group of 4 lanes each physical lane can be

configured logically as lane 0, lane 1, lane 2 or lane 3.

This device is MCDA-ML compatible, offering inter lane alignment between several devices. An IDT proprietary mechanism

in combination with the JESD204B subclass I clause enables maintenance of sample alignment between devices up to the

final analog output stage. Output samples are automatically aligned to the SYSREF signal generated by a dedicated IC or

DAC1653Q/DAC1658Q

Advance data sheet

by the FPGA itself. A system with several DAC165xQs can produce data with a guaranteed alignment of less than

+/-1 DAC output clock period. The DAC165xQ incorporates two differential SYSREF ports (located on opposite sides of the

IC) to simplify the PCB layout design. The device also enables independent link reinitialization.

The DAC165xQ generates four complementary current outputs on pins IOUTA_P/IOUTA_N and IOUTB_P/IOUTB_N,

IOUTC_P/IOUTC_N, and IOUTD_P/IOUTD_N corresponding to channel 'A', ‘B’, ‘C’, and 'D', respectively, providing a

nominal full-scale output current of 20 mA. An internal reference is available for the reference current which is externally

adjustable using pin VIRES.

The DAC165xQ requires configuration before operating. It features an SPI slave interface to access the internal registers.

Some of these registers also provide information about the JESD204B interface status. Optionally, an interrupt capability

can be programmed using those registers to ensure ease of use of the device.

Because of the JESD204B standardization, the DAC165xQ does not require any adjustment from the Transmit Logic

Device (TLD) to capture the input data streams. Some autolock features can be monitored using the SPI registers.

The DAC165xQ supports the following LMF configuration as described in the JESD204B standard (register

XY_LMF_CNTRL (00DEh 02DEh 04DEh)):

[1] S is the number of samples per frame.

[2] HD is the high-density bit as described in the JESD204B specification.

A new IDT auto-mute feature enables switching off of the RF output signal as a result of various internal events occurring.

A signal level detector allows auto-muting of the DAC outputs if they exceed the detection limit.

The DAC165xQ requires 3.3 V and 1.2 V power supplies. The 1.2 V supply has separate digital and analog power supply

pins.

In order to program the device in LMF841 (SLQ) configuration, each DAC AB and DAC CD instance of XY_LMF_CNTRL

registers will have to be programmed in LMF421. In parallel, SLQ configuration (common ILA, common sync) must also be

selected. Same apply, in order to get SLQ LMF842/LMF442/LMF244 configuration, LMF422/LMF222/LMF124 will have to

be programmed for each dual DAC.

11.2.1 SPI configuration block

This block of registers specifies how the SPI controller and the identification of the chip work.

11.2.1.1 Protocol description

The DAC165xQ serial interface is a synchronous serial communication port allowing easy interfacing with many industry

microprocessors. It provides access to the registers that define the operating modes of the chip in both Write mode and

Read mode. The reference voltage of the interface is VDDD(IO). Depending on the power supply level of the SPI master

device, it can be set from1.2 V to1.8 V.

This interface can be configured as a 3-wire type (SDIO as bidirectional pin) or a 4-wire type (SDIO and SDO as

unidirectional pins, input and output ports, respectively). In both configurations, SCLK acts as the serial clock and SCS_N

acts as the serial chip select.

The DAC165xQ SPI-interface is a slave-device. Multiple slave-device can be attached to the same master interface as long

as each device has its own serial chip select signal (SCS_N).

Quad 16-bit DAC: 10 Gbps JESD204B interface: x2, x4 and x8 interpolating

Advance data sheet

A[14:0] indicates which register is being addressed. If a multiple transfer occurs, this address points to the first register to

be accessed.

11.2.1.2 SPI controller configuration

The 3-wire or 4-wire mode is set by bit SPI_4W of register SPI_CONFIG_A (0000h). The default mode is 3-wire mode.

A software SPI reset can be called via bit SPI_RST (0000h). This reset reinitializes all SPI registers, except register

SPI_CONFIG_A and SPI_CONFIG_B, to their default settings. Only a hardware reset on pin RESET_N can reset to their

default values. Reset the device to its default value at start-up time to avoid any uncontrolled states.

The SPI streaming mode is enabled by default. In this mode, the Read or Write process carries on as long as the SCS_N

signal is low. The streaming mode requires a first address 'n' to be set at the beginning of the SPI sequence. The following

data are associated from this address in an ascending (auto-increment) or descending (auto-decrement) mode. This

ascending/descending mode is specified by bit SPI_ASCEND (0000h). Figures below represent the readback of 2 bytes

data in a 3 wires mode for the ascendant and descendant mode.

The streaming mode can be disabled by setting bit SPI_SINGLE (0001h). In this single-byte mode, only 1 byte of data can

be written or read, whatever the state of the SCS_N signal.

R/W indicates the mode access.

The RESET_N signal is not linked to the SPI interface but enable the reset of the registers to the default values.

11.2.1.3 SPI register map

The DAC165xQ includes two dual DAC core. In order to ease access to each dual DAC of the device, the register map

implementation enables to either access DAC AB , DAC CD or both using a single write:

• Adress from 040h to 1FFh is reserved for dual DAC AB.

• Adress from 240h to 3FFh is reserved for dual DAC CD.

• Adress from 440h to 5FFh is reserved for dual write access to both DAC AB and DAC CD (only write access possible).

• Adress from 00h to 03F is reserved for common device register.

DAC AB register are ordered in same way than DAC CD register. So if a function for DAC AB is available at address n, the

same function is available at address n+ 200h for DAC CD. writing to address n+400h enables to simultaneously set this

function for both dual DAC.

11.2.1.4 Double buffering and Transfer mode

Some register functions (like the NCO frequency value) are split over multiple registers. If this is the case, the first address

consists of the LSB byte and the highest address in the MSB byte. When programming these registers sequentially, some

unexpected behavior can occur at the DAC output. It is preferable to program this set of registers simultaneously. A double

buffering feature is available on some registers allowing sequential programming of the first buffers and transferring the

values to the final register simultaneously.

The transfer request is done by setting the TRANSFER_BIT bit of register SPI_CONFIG_C register (000Fh). The device

clears this bit (autoclear) indicating to the SPI master device that the transfer is complete.

The SPI_READBUF bit (0001h) allows the reading back of the first stage of buffers (in case the register is double buffered).

The following registers are double buffered:

[1] The RESET_N signal is asynchronous to the SPI interface, but enables the reset of the registers to the default values.

11.2.2 Power up sequence

There are four steps for the power-on sequence (see Figure 32):

1. all supplies and clock are switched on. at Ton time (see Figure 32), all DAC165xQ supplies have reached their

specification ranges and the device clock CLKIN is up and running.

2. Then a wait duration of 1 s is needed before releasing the RESET_N pin.

3. Then a wait duration of 40k periods of device clock CLKIN is needed before sending the first SPI device configuration

command. So for example a 40μsec wait period is needed when Fclkin= 1 GHz.

4. At start-up, the three clocks WCLK, DCLK and PCLK are forced to reset states to avoid that the DAC outputs any

dummy signal through bits FORCE_RESET_WCLK, FORCE_RESET_DCLK and FORCE_RESET_PCLK of the

MAINCONTROL register (0020h). The PCLK clock are only used in case of the PLL usage. Refers to the PLL

configuration section to know how to program it correctly. The default mode described in following section is when the

Device clock is used as sampling clock (DAC PLL OFF). In this case the bit FORCE_RESET_PCLK is kept enabled.

11.2.3 Main device configuration and SPI Start-up Sequence

The registers of block MAIN are used for the main configuration of the DAC165xQ.

•

Here are some guidelines to ensure basic correct SPI programming. As DCLK and WCLK are kept to reset, the

programming sequence of the registers is not important after the reset:

1. Put PLL in low power mode (needed only if PLL is not used).

2. Proceed to a software reset of all SPI registers (see Section 11.2.1.2)

3. Disable Pin RF_ENABLE Power Down mode (optional)

4. Specify the Clock Domain Interface (CDI) mode (Section 11.2.7.1 and Table 26) and the Interpolation mode (see

Table 16) and/or SSBM mode (see Table 18)

5. Set the SYNCB pin control, output common mode level and swing (see Section 11.9.5.5)

6. enable JESD204B HF_REF module.

7. Specify the Clocks configuration (see Section 11.2.7.1):

a. Divider bypass or Divider mode

b. WCLK division ratio

8. Specify the JESD204B LMF configuration (see Section 11.9.5.10)

9. Specify the JESD204B logical lanes order (see Section 11.9.5.3) and polarity

10. Specify which JESD204B physical lanes have to be turned off using the POFF_RX bits of register POFF

11. Define JESD204B ILA control and scrambling.

12. Define Mute control option.

13. Release the WCLK and DCLK reset by de-asserting the bits FORCE_RESET_DCLK and FORCE_RESET_WCLK of

the MAINCONTROL register (0020h)

Advance data sheet

Remark: All the Double Buffering registers programmed before the DCLK reset release are transfered automatically after

the DCLK reset release. After this reset release, these registers need the TRANSFER_BIT to be active.

11.2.3.1 SPI start-up sequence example

The following SPI sequence shows the list of commands to be used to start the DAC165xQ in DLQ (Dual link Quad)

configuration, LMF222 with interpolation 4 mode with NCO off, PLL bypass mode, and without inverse (sin x) / x.

Other start-up sequences can be easily derived from this sequence:

11.2.4 Interface DAC DSP block

This module is the interface between the data processing in the high-speed serial receiver and each of the dual DAC core.

The controls of the Digital Signal Processing (DSP) of the DAC are specified to set up the interpolation filter, and enable or

disable the various gains and offsets of the data digital path. The data signals have already been processed by the Digital

Lane Processing (DLP, see Section 11.9.3). They are provided to this module through the Clock Domain Interface

(Section 11.2.7.1). This module is clocked by the digital clock DCLK.

11.2.4.1 Input data format

After decoding in the high-speed serial receiver, the data representation can be specified as binary offset coding or as two's

complement coding using register XY_DATA_FORMAT (0075h 0275h 0475h).

11.2.4.2 Finite Impulse Response (FIR) filters

The DAC165xQ provides three interpolation filters described by their coefficients in Table 17. The three interpolation FIR

filters have a stop band attenuation of at least 80 dBc and a pass band ripple of less than 0.0005 dB.

The interpolation ratio can be set through register XY_TXCFG (0060h 0260h 0460h).

The 'no interpolation' or '~1' (quasi 1) mode is in fact a degenerated 2 interpolation mode where the samples are

repeated twice.

Remark: The XY_INT_FIR[1:0] setting must be coupled with the DCLK and WCLK clock configurations and with CDI mode

(see Section 11.2.7.1).

Advance data sheet

The effect of the XY_MODE[2:0] parameter is better viewed after mixing the X and Y signal with a LO frequency through an

IQ modulator.

11.2.4.4 40-bit NCO

The SSBM used the complex signals coming from the NCO (Numerically Controlled Oscillator) to mix the I and Q signals.

The 5 registers XY_FREQNCO_B0 to XY_FREQNCO_B4 over 40 bits (0064h 0264h 0464h to 0068h 0268h 0468h) can

set the frequency.

The frequency is calculated with Equation 1:

(1)

Where:

•XY_FREQ_NCO is the value set in the registers XY_FREQ_NCO[39:0].

•fs is the final DAC output clock sampling frequency

The registers XY_PHINCO_LSB and XY_PHINCO_MSB over 16 bits from 0 to 360 (0062h 0262h 0462h / 0063h 0263h

0463h) can set the phase of the NCO.

11.2.4.5 NCO low power

When using NCO low power (bit XY_NCO_LOWPOWER; 0060h 0260h 0460h), the five most significant bits of register

XY_FREQ_NCO[39:0] can set the frequency (bits [31:0] are masked by zero).

The frequency is calculated with Equation 2:

(2)

Where:

•XY_FREQ_NCO is the value set in the masked bits XY_FREQ_NCO[39:0] of the NCO frequency registers

•fs is the DAC output clock sampling frequency

11.2.4.6 Minus 3dB

During normal operation, a full-scale pattern is also full-scale at the DAC output. When the I data and the Q data approach

full-scale simultaneously, saturation can occur. The Minus 3dB function (bit XY_MINUS_3DB_GAIN of register

XY_DSP_OUT_CNTRL; 006Fh 026Fh 046Fh) can be used to reduce the 3 dB gain in the modulator. It retains a full-scale

range at the DAC output without added interferers.

11.2.4.7 Phase correction

The IQ modulator which follows the DACs can have a phase imbalance resulting in undesired sidebands. By adjusting the

phase between the I and Q channels, the unwanted sidebands can be reduced.

Without compensation the I and Q channels have a phase difference of  / 2 (90°). The registers

XY_PHASECORR_CNTRL0 and XY_PHASECORR_CNTRL1(0069h 0269h 0469h and 006Ah 026Ah 046Ah) ensure a

phase variation from 75.7 to 104.3 by steps 0.0035. The two registers define a signed value that ranges from 4096 to

+4095. The equation: PH_CORR[12:0] / 16384 gives the resulting phase compensation (in radians). The phase correction

can be enabled by register XY_PHASE_CORR_ENABLE.

11.2.4.8 Inverse sin(x) / x

A selectable FIR filter is incorporated to compensate the sin(x) / x effect caused by the roll-off effect of the DAC. The

coefficients are represented in Table 19. This feature is controlled by register XY_INV_SINC_EN (0060h 0260h 0460h).

Remark: The transfer function of this features adds some gain to the signals and some saturation can occur with a level of

distortion in the output spectrum as result. Update the digital gain accordingly to avoid this saturation.

11.2.4.9 Digital gain

The full-scale output current for each DAC is the sum of the two complementary current outputs:

•

The IQ-modulator can have an amplitude imbalance which results in undesired sidebands. The unwanted sideband can be

reduced by adjusting the amplitude of signals A and B. The two gains are purely digital and could be enabled by registers

XY_DSP_X_GAIN_EN and XY_DSP_Y_GAIN_EN (006Fh 026Fh 046Fh).

The output current of DAC A depends on the digital input data and the gain factor defined by registers

XY_DSP_X_GAIN_MSB and XY_DSP_X_GAIN_LSB (006Bh 026Bh 046Bh and 006Ch 026Ch 046Ch).

(3)

(4)

The output current of DAC Y depends on the digital input data and the gain factor defined by registers

XY_DSP_Y_GAIN_MSB and XY_DSP_Y_GAIN_LSB (006Dh 026Dh 046Dh and 006Eh 026Eh 046Eh).

DAC1653Q/DAC1658Q

Quad 16-bit DAC: 10 Gbps JESD204B interface: x2, x4 and x8 interpolating

Advance data sheet

In normal operating mode, the state machine is in IDLE state. The digital gains are specified by the user.

Various mute events can be detected in the DAC. These trigger the MUTE state. Once the MUTE state is entered, the DAC

automatically sets the digital gains to zero using several mute actions. The SOFT mute and HOLD mute drops to zero

gradually. The HARD mute drop to zero instantly (see Figure 44).

When the digital gains have been set to zero, the state machine enters the WAIT state. In this state, the gains are kept at

zero. The state machine stays in this mode until the end of the wait period and the mute event is not de-asserted.

When the mute event is cleared and the wait period has elapsed, the state machine enters the DEMUTE state. In this state,

the digital gains are set again to the initial values. This is done relatively to the mute rate setting. If during this state, a new

mute event is triggered, the state machine enters the MUTE state again. The gain decreases from the current gains values,

not from the initial ones.

When the digital gains reach the initial values, the state machine enters the IDLE state again.

The mute feature is set by enabling bit XY_MUTE_ENA in register XY_MUTE_CNTRL_0 (see Table 82).

Mute events

The MUTE action is triggered by one of the following mute events. Each of them is linked to either an error detection, a

status change or signal power monitoring:

•SW_MUTE:

Software event that can be requested by the host interface through the SPI bus.

•RF_EN:

Hardware event that can be requested by the host interface through pin RFTX_ENABLE (= IO1)

•CLK_MON (XY_MC_AL_ENA[0]):

Event linked to the monitoring of the clocks in the receiver physical layer control block.

•MON_DCLK_ERR:

Event triggered when a clock error occurs in the CDI (see Section 11.2.7.1).

•CA_ERR:

Event triggered when a clock error occurs in the DLP (see Section 11.9.3).

•TEMP_ALARM:

Event triggered when the temperature sensor measures a temperature that exceeds the threshold value.

TEMP_SEL_MAN must be specified first.

•ERR_RPT_FLAG:

Event triggered when error report flag is detected by the DLP (see Section 11.9.3).

•CLIP_DET:

Event triggered when the signal levels exceed the XY_CLIPLEV level on channel X or Y. XY_CLIPDET_ENA,

XY_CLIP_LEV_EN and XY_CLIP_SEL LVL_DET_XY must be set first.

•MDS_BSY:

Event triggered while the MDS process is busy with capturing the SYSREF (see Section 11.8.3).

•DATA_IQ_VALID:

Event is triggered when DATA_INVALID is detected by the DLP (see Section 11.9.3)

•SPD_OVF:

Event triggered when the Signal Power Detector (SPD) average value is exceeding the threshold value

(Section 11.2.5.2).

•IQR_ERR:

Event triggered when the IQ signal is out of range (see Section 11.2.5.3).

The monitoring of these events can also be done using the interrupt process available in the DAC165xQ (see Section 11.9).

Once the interrupt is detected, the host controller (e.g. an FPGA) can read back the events flags in registers

XY_INTR_FLAGS_0 and XY_INTR_FLAGS_1 and determine the actions to be taken.

Ignore events option

Set bits XY_IGNORE_RFTX_ENA, XY_IGNORE_MDS_BSY, and XY_IGNORE_DATA_V_IQ of the mute control register

for the mute controller to ignore certain events.

Mute event categories

The MUTE state is entered when one of the mute events is asserted. Four categories of mute events can be distinguished:

ALARM, DATA, INCIDENT, and DIRECT. For each categories specific mute action could be selected. The control of these

events is summarized in Table 21

[1] All ALARM mute events can be disabled using bit XY_IGNORE_ALARM. However, their detection can still be monitored using the INTERRUPT

module.

[2] This bit is not auto-clear.

[3] The ALARM mute events must be cleared with bit XY_MC_ALARM_CLR to move from the WAIT state to the DEMUTE state.

Priority between categories

•The priority in which the Auto-mute module evaluates its inputs is:

•Priority 1: DIRECT

•Priority 2: ALARM

•Priority 3: DATA

•Priority 4: INCIDENT

Mute actions

Four mute actions can be selected for each of the four previous mute event categories.

•Hard_mute + mute IQ:

The digital gains of the DACs are set to zero immediately (within 1 DAC clock period). The digital path is filled with the

default I and Q levels value (defined with register XY_I_DC_LEVEL[15:0] and XY_Q_DC_LEVEL[15:0]) to avoid

disturbances in the FIR filters.

•Hold_mute + mute IQ:

The outputs of the DACs are kept to the latest good value (within 1 DAC clock period). The digital path is filled with the

default I and Q levels value (defined with register XY_I_DC_LEVEL[15:0] and XY_Q_DC_LEVEL[15:0]) to avoid

disturbances in the FIR filters.

Remark: Bit XY_HOLD_DATA must be enabled for this action. If this bit is not set, the overall Hold_mute + mute IQ

actions are not taken into account.

•Soft_mute + mute IQ:

The digital gains of the DACs are swept down to zero at the mute rate value. The digital path is filled with the default I

and Q levels value (defined with register XY_I_DC_LEVEL[15:0] and XY_Q_DC_LEVEL[15:0]) to avoid disturbances in

the FIR filters. The DAC165xQ provide the possibility to use different mute rate for incident/data/alarm/direct mute

category (using registers XX_ALARM_MRATE / XX_DIRECT_MRATE / XX_INCIDENT_MRATE/ XX_DATA_MRATE).

But for proper operation all these registers must be set with same value.

•Soft_mute:

The outputs of the DACs are swept down to zero at the mute rate value. The digital path is kept with the received

values.

Remark: As the DC offsets are applied after the digital gain, the outputs are still impacted by their values, even if a

mute action event occurs.

Remark: The time period used to decrease or increase the gains during a MUTE or DEMUTE state is called mute rate.

Device implementation enables to have for each mute action category, its own mute rate through the registers

XX_ALARM_MRATE / XX_DIRECT_MRATE / XX_INCIDENT_MRATE/ XX_DATA_MRATE. But for proper operation all

these registers must be set with same value. The Table 22 gives the mute time corresponding to possible registers value.

Mute wait period

The wait period time can be calculated with Equation 7:

(7)

At 1 Gsps, this gives a wait period between 8 ns and 527 s.

DEMUTE triggering

When the mute action is either a DIRECT, an INCIDENT or a DATA mute action, the WAIT state is enabled as long as the

wait period is not elapsed and the event is not released.

When the mute action is an ALARM mute action, the WAIT state is enabled as long as the alarm controller is not reset

using bit XY_MC_ALARM_CLR.

11.2.4.11 Digital offset adjustment

When the DAC165xQ analog output is DC connected to the next stage, the digital offset correction (bits

XY_DSP_X_OFFSET[15:0] and XY_DSP_Y_OFFSET[15:0]) can be used to adjust the common-mode level between

IOUTxN and IOUTxP pins at the output of each DAC. Table 23 shows the variation range of the digital offset.

Care should be taken when adding DC offset to large signal.The resulting signal might exceeds the 16 bits dynamic of the

DAC.

11.2.5 Signal detectors

11.2.5.1 Level detector

A level detector feature is available at the end of the digital path. It can be enabled using bit XY_CLIP_LEV_EN. This

feature specifies a signal output range limited (or clipped) to 128  LVL_DET_XY to +128  LVL_DET_XY around the half

Full-Scale (FS) . If the signal value enters the upper or lower clipping area, it is clipped to +128  LVL_DET_XY or

128  LVL_DET_XY, respectively). Figure 45 shows this behavior.

Use this feature in combination with the auto-mute feature to avoid unexpected spectral spurs after the clipping of the signal

(see Section 11.2.4.10).

11.2.5.2 Signal Power Detector (SPD)

The Signal Power Detector (SPD) takes the 7 MSBs of the I and Q signal to determine the IQ power of an IQ-pair.

Averaging is done over the programmable number (26, 27 to 221) of IQ-pairs using the XY_SPD_WINLENGTH register. If

the average value (readable in register XY_SPD_AVERAGE) exceeds the 16-bits threshold value (defined in register

XY_SPD_THRESHOLD), the SPD overflow (SPD_OVF) flag becomes active and can invoke a mute action depending on

the mute control settings.

The SPD can have a large response time because of the samples average based algorithm. This must be taken into

account at system level.

11.2.6 Pin RF_ENABLE

A RF_ENABLE/IO1 pin is available to powerdown the analog output of the DACs. The shutdown consists in a MUTE

request on the MUTE controller. This trigger is active low and is part of the direct mute events container (see

Section 11.2.4.10). by default this feature is enabled. This means that to enable the DACs output, a signal high needs to be

applied on the pin. When applying a signal low, the MUTE controller will mute the DACs output.

The following registers must be set to configure pin IO1 in RF_ENABLE mode (these are the default values at start-up

time):

•IO_ENA[1] must be set to '0' to set the pin to input mode.

•XY_IGNORE_RFTX_ENA must be disabled to allow the triggering of the event

•RFTX_ENA_PD_ANA_CD and RFTX_ENA_PD_ANA_AB bits must be enabled

11.2.7 Analog core of the DAC

This section refers to the analog configuration required to set up the dual DAC core. The clock and output stages are

described as well as the internal registers (Block x0020; see Figure 48 and Table 49) used to configure the clock tree

inside the chip.

11.2.7.1 Clocks

The DAC165xQ requires one single differential clock (CLKIN_P, CLKIN_N) for the whole device (including the digital data

path, the DAC core and the JESD204B interface).

During the reset phase (RESET_N asserted), the input clock must be stable and running, ensuring a proper reset of the

complete device.

On-chip Phase-Locked Loop (PLL)

The DAC165xQ has a single differential clock input to directly feed the digital and analog clock tree of the device. When

using the embedded PLL, a reference clock has to be provided at this input. The mixed-signal PLL synthesizes the correct

internal clocks with very low jitter. Figure 49 shows a conceptual view of the PLL. Digital control words that control the

oscillator frequency determine the output frequency of the PLL:

•

The pre-divider (Pr) and post-divider (Po) can be programmed in order to generate targeted DAC sampling frequency. The

DAC sampling clock frequency can be calculated with Equation 8:

(8)

The DCO clock frequency can be calculated with Equation 9:

(9)

The DAC165XQ includes a DCO center frequency tuning capability. To get wide DCO frequency compliance range (as

described in Table 6), it recommended to program ADPLL_DCO_CTF[7:0] register with the value given by Equation 10

(round result in order to have min value =0 max value=0x0F):

(10)

In order to get a valid combination of FCW, Pr and Po, the compliance range for both Fref (=Fclkin/N) and Fdco as defined

in Table 6 must be considered. Table 25 give some examples of valid combinations:

•

Clock input external configuration

The DAC165xQ incorporates one differential clock input, CLKIN_N/CLKIN_P, with embedded 100  differential termination

resistor. The clock input can be LVDS but it can also be interfaced with CML.

The clock input buffer is self biased. An AC coupling circuit is recommended as shown in Figure 50. The minimum

requested differential voltage is given in Table 6 but a higher voltage swing of 1000mVpp,diff will give better results.

Clock frequency input range

The DAC165xQ can only operate in two modes:

•Direct clocking mode:

The input clock frequency is limited to 2000 MHz

•Divided clocking mode:

The input clock is internally divided by 2, 4, 6, or 8. The maximum input frequency is 3 GHz. This mode allows the

programming of the group delay feature.

Clocks internal configuration

The following registers must be specified to configure the DAC165xQ clocking mode:

•CLKGENCFG1 to specify the WCLK configuration.

•CLKDIV_CFG to specify the DCLK configuration and the divider / group delay feature.

•PON_DCKDIV_CFG to power on the clock divider (required only for divided clock) (see Table 55)

The final clock is referred to as the "DAC clock". This is the clock that is going directly to the DAC core and is running at

maximum speed. From this DAC clock two digital clocks are derived: DCLK and WCLK.

DCLK is the digital clock used for all logic related to the Digital Signal Processing (DSP) of the DAC.

WCLK is the digital clock used for all logic related to the Digital Lane Processing (DLP) of the input interface. The divider

ratio WCLK_DIV_SEL (see Table 54) must be specified using the following equation:

(11)

Where:

•M stands for the number of DACs used inside the dual core DAC (=2).

•L stands for the number of serial input lanes used (L = 1, L = 2, or L = 4)

•INTERPOLATION stands for the interpolation factor specified in registers XY_TXCFG and CDI_CNTRL.

Clock divider and Group Delay configuration

To enable the Clock division, the dividers biasing should be powered on using PON_CGFG_NC. Then the division ratio

CLK_DIV_SEL needs to be configured and the default bypass mode must be disabled (CLK_DIV_BYPASS register ). In

this mode, the CLKDIV_SEL_PHASE bits are used to specify the group delay phase. The CLKDIV_SEL_DIV must be set

during the DAC initialization phase only (see Table 57).

When changing the DAC clock phase during nominal usage, the DAC output will be kept at the previous value while the

new phase is set. For instance, setting the DAC clock phase from setting 0 to setting 1 will imply a 1.5 DAC clock constant

value. No glitches are expected during this phase.

Clock Domain Interface (CDI)

A CDI logic handles the error-free data transition from the WCLK clock domain to the DCLK domain. It consists of 12

buffers that absorb the phase variation between the two clocks. The reliability of the data transmission depends on the

clock-frequency ratios and therefore on the interpolation mode. The CDI must be set in the same mode as the interpolation

ratio to be properly configured. This mode is configured with register CDI_CNTRL.

Ideally, buffer number 11 is selected as the reference. If jitter of +/- 1 clock cycle is injected between the clocks occurs, the

pointer can oscillate between buffers 10 and 0. If more jitter is injected, the range increases to buffers 9 and 1, etc.

This buffer position can be monitored using register MON_DCLK_AB and MON_DCLK_CD flags.

The variation of the buffer location could also raise an interrupt (see Section 11.9).

11.3 Overall Latency

The implementation of the different features of the DAC165xQ imply a different latency regarding the mode used. This

latency is dependent of the following features:

1. the LMF-S configuration

2. the Interpolation mode

3. the Phase Correction usage

4. the SSBM/NCO usage

5. the InvSin(x)/x usage

The total latency is expressed in DAC clock cycles and could therefore be scaled regarding the DAC clock frequency used.

Moreover, the values of the table are showing the uncertainties due to the internal design implementation. There are two

buffers/fifo that are used to compensate the skew between the lanes (see registers XY_ILA_MON_L_LN xx ) and to delay

aligned (XY_ILA_MON_L_LN xx= 8 by default) and the XY_MDS_MAN_ADJUSTDLY is set to 0 (minimal delay). See

Table 30 for additional delays.

Remark: The overall latency values are given when the MDS feature is not used.

11.4 Analog quad DAC core

The DAC165xQ core consists of four DACs. Each of them can be independently set to Power-down mode dedicated

when DAC A is not used (but other DACs are still used), to only power down DAC A core and DAC A commutator using bit

XY_PON_DAC_X and XY_PON_COMM_X of register XY_PON_DDCCFG_0.

11.4.1 Regulation

The DAC165xQ reference circuitry integrates an internal band gap reference voltage which delivers a 0.7 V reference on

the GAPOUT pin. Decouple pin GAPOUT using a 100 nF capacitor.

The reference current is generated via an external resistor of 562  (1 %) connected to VIRES pin.

Figure 52 shows the optimal configuration for temperature drift compensation because the band gap reference voltage can

be matched to the voltage across the feedback resistor.

The DAC current can also be adjusted by applying an external reference voltage to the non-inverting input pin GAPOUT

and disabling the internal band gap reference voltage (bit PON_GAP of register PON_CFG_NC).

11.4.2 Full-scale current adjustment

The default full-scale current (IO(fs)) is 20 mA. However, further adjustments, ranging from 10 mA to 30 mA, can be made to

each DACs independently using the SPI interface. The registers values allowed to reach lower and higher current values

but those values are out the range that maintains the typical dynamics performances.

The settings applied to XY_CSA_BIAS_X[9:0] and XY_CSA_MULT2_X define the full-scale current of DAC X:

11.6 Auxiliary DACs

Each DAC output of the DAC165xQ is internally connected to auxiliary DACs, which are used to compensate any offset at

DACs output (useful for example in order to compensate IQ modulator LO leakage). DAC1658Q auxiliary DACs sink

current (referenced to VDDA(out) ). DAC1653Q source current (referenced to ground). Auxiliary DACs have a 10-bit

resolution.these auxiliary DACs can be disabled using bits XY_PON_AUX_DAC_X and XY_PON_AUX_DAC_Y of the

XY_AUX_CFG_X_0 and XY_AUX_CFG_Y_1 Auxiliary DACs registers.

TEMPS_LEVEL specifies the threshold level that is compared with the measured value. If the measured value exceeds the

threshold, the TEMP_ALARM flag is set and triggers a mute action (see Section 11.2.4.10). The maximum and minimum

temperatures measured are stored in registers TEMP_MAX and TEMP_MIN respectively. The current temperature is

stored in register TEMP_ACTUAL. Once the TEMP_ALARM flag is set, it must be reset using the TS_RST_ALARM bit of

the temperature sensor control register. The maximum and minimum temperature can also be reset using bits

TS_RST_MAX and TS_RST_MIN of the temperature sensor TEMPS_CNTRL register.

The value stored in the TEMP_MAX, TEMP_MIN and TEMP_ACTUAL registers represents the output value of the ADC.

This value could be converted in real die temperature using Equation 16.

11.8 Multiple Device Synchronization (MDS); JESD204B subclass I

The MDS feature enables multiple DAC channels to be sampled synchronously and phase coherently to within one DAC

clock period. This feature is part of the JESD204B standard but the implementation adds some unique features that simplify

the PCB design.

11.8.1 Non-deterministic latency of a system

In a system using multiple DAC devices, there are numerous sources of timing uncertainties. Figure 56 gives an overview

of these uncertainties.

The sources of uncertainties are shared between the Transmitter devices (TX), the Receiver devices (RX), the PCB layout

and the architectures of the JESD204B system clocks. A single device can detect timing drift and uncertainties, but not at

system level. Therefore a synchronization process is required to enable the system to output the analog signals of all the

RX devices in a coherent way. Moreover, the system becomes predictable if from one start-up to another one, the overall

latency is deterministic.

The MDS feature of the DAC165xQ has been implemented in accordance with the JESD204B subclass 1 specification to

fulfill these requirements.

11.8.2 JESD204B system clocks and SYSREF clock

There are various system 'clocks' that are used in the JESD204B specification. However, only one of them is seen at

system level, the device clock, which is provided to the device. The other clocks are related to the JESD204B standard and

are used to assemble/de-assemble the data in octets and then in 10 bits words (see JESD204B standard). Figure 57 and

Table 32 show the relationship between them.

As all clocks can be derived from the Multi-Frame Clock (MFC), this clock becomes the reference for a JESD204B system.

Each device used in the system has its own local version of the MFC. These local version are called Local Multi-Frame

Clock (LMFC). Due to the timing uncertainties the phase relationships between all the device LMFCs are unknown. The

goal of MDS is to be able to realign all LMFCs in a deterministic and accurate way.

To align all the LMFCs within the system, a new clock named SYSREF (SYStem REFerence) is used. This clock is linked

to the multi-frame clock by a divided ratio R, therefore it is a low frequency signal.

The SYSREF signals must be propagated to all the devices of the system. They are used as a timing reference to align the

internal LMFC of each devices. To ensure that all phases of the signals are aligned at the source, the SYSREF signals and

the device clocks must be generated from the same clock IC (see Figure 58). The appropriate clock device could be found

within the IDT Timing Division unit portfolio.

All the JESD204B devices will capture their SYSREF signal and use it to align their datastream/LMFC. The edge detection

of the SYSREF signal is used as a system timing reference and the device align their LMFCs phase to the closest edge of

the SYSREF. To ensure an accurate alignment within all devices, the SYSREF signal must show the same phase at the

input port of all the devices to synchronize. Therefore, the trace lengths of the SYSREF signals must be equal for all the

DAC devices.

The DAC165xQ embeds updated SYSREF buffers. Both West and East side can use the incoming SYSREF signal

asynchronously to remove the uncertainties due to the sampling moment inside each devices. There is no more setup and

hold constraint on the SYSREF signal in asynchronous mode.

The following figure shows the virtual LMFCs before and after alignment to the SYSREF clock.

The DAC165xQ MDS implementation is based on two modules as described in Figure 60:

•M1:

This module contains the SYSREF detector and the control loop used to create a LMFCMDS signal. The control loop is

clocked with the digital clock. The digital clock equals DAC clock / 8.

•M2:

This module compares the phase of the LMFCRCV received from the JESD204B digital lane processing to the phase of

the LMFCMDS and shifts the position of the buffer to align the data path to the LMFCMDS.

11.8.3.1 Capturing the SYSREF signal

Module M1 ensures the capture of the SYSREF signal at DAC clock accuracy. This is done by an early-late detector and a

control-loop. The control-loop must capture several SYSREF edges to deliver an accurate LMFCMDS signal to the M2

module. The Initialization of the control-loop is triggered by the edge detection of the SYSREF signal (see Figure 61). The

capture is done during the capture window and is repeated at the end of every control loop period until the signal is locked.

The SYSREF edge must occur within the capture window.

Figure 62 shows an example on how to set up the M1 module.

Fig 60. Modules of MDS implementation

In this example the SYSREF period is twice the LMFC period (R=2)

The DAC165xQ requires the following parameters:

•LMFC_PERIOD register:

Period of the LMFC in digital clock cycles (e.g. 8  8 ns)

•Capture window and control loop period:

These are specified using XY_MDS_WIN_HIGH and XY_MDS_WIN_LOW registers (respectively at address

0x0A9/0x2A9/0x4A9 and 0x0A8/0x2A8/0x4A8). They are expressed in digital clock cycles and must be set using the

following equations:

Remark: The capture window must be smaller than the SYSREF period.

At the end of the capture process, the LMFCMDS signal is provided to the M2 module and the XY_MDS_LOCK bit of the

XY_MDS_STATUS2 status register is set to 1. If the M1 module cannot lock, the MDS_I_BUSY flag of register

XY_MDS_STATUS1 is kept high and a mute action can be held (see Section 11.2.4.10).

11.8.3.2 Aligning the LMFCs and the data

Module M2 ensures the phase alignment of the LMFCRCV to the closest LMFCMDS edge. The LMFCRCV is issued from the

digital lane processing by analyzing the ILA sequence using the multi-frames /A/ symbols present. The transmitter (TX) is

expected to have its self-synchronization process to the global MFCSYSTEM. It generates the ILA sequence based on the

aligned LMFCTX. The total latency of the link is compounded of a fixed value (due to PCB traces, devices internal fixed

delays, etc.) and a random value (due to elastic buffers, clocks domains interface, etc.). By buffering the data and the

LMFCRCV after the initial-lane alignment process, the M2 module is capable to adjust the position of the buffer delay to

match the recovered LMFCMDS.

Figure 63 shows the alignment process for two links. The two links have two different total latencies but due to the LMFCTX

and LMFCMDS phase synchronization to the MFCSYSTEM, the various devices are capable to align to the same MFCSYSTEM

edge in a fixed and deterministic way.

Take special care when selecting the MFCSYSTEM period. A longer period is better than a short one. In general, the

MFCSYSTEM period must be at least two times the maximum latency between devices to avoid a wrong edge selection as

shown in Figure 64.

11.8.3.3 Monitoring the MDS process

The buffer adjustment performed using the M1 and M2 modules can be read back using the XY_MDS_ADJDELAY register.

Bits 7 to 3 of this register represent the coarse delay expressed in digital clock cycles whereas bits 2 to 0 represent the fine

adjustment in DAC clock cycles. The buffer adjustment has a default value of 80h.

MDS_LOCK bit of register XY_MDS_STATUS2 is set to 1 when the MDS process is completed. You can use this bit to

check if the device is aligned to the SYSREF.

11.8.3.4 Adding adjustment offset

The DAC165xQ allows adding an offset on top of the automatic adjustment. This is available via register

XY_MDS_OFFSET_DLY. The offset range is from 16 to 15 digital clock cycles. This offset value can be set at the start-up

time as well as in at later period. This enables compensating a layout error or adding a specific phase to one DAC device.

Another adjustment delay can be set but only after a first automatic alignment using the manual adjustment delay register

XY_MDS_MAN_ADJUSTDLY with a resolution of DAC clk.

11.8.3.5 Selecting the SYSREF input port

The DAC165xQ incorporates two SYSREF differential ports: SYSREF_E_P/N (East side of the device) and

SYSREF_W_P/N (West side of the device). One of these ports can be selected as the input for the SYSREF signal and will

be capture in an asynchronous way.

Remark: SYSREF signal is only needed during SYNC_Request periods. The signal should/could be switched off later to

avoid analog disturbances.

has an optional internal differential resistor termination of about 100 . This resistor can be enabled with registers

MDS_SEL_RT_E and MDS_SEL_RT_W. Polarity could also been switched using MDS_SYSREF_POL_W and

MDS_SYSREF_POL_E bits. Please note that only SYSREF_W input support resynchronization mode to clkin using

11.8.3.6 MDS script example

Here are some guidelines to ensure basic correct MDS SPI programming (based on default register settings). This

sequence must be applied before DCLK and WCLK resets are released (step 14 in Section 11.2.3.1):

1. Specify the asynchronous mode and the polarity expected for East and West input by asserting the bits of register

MDS_IO_CNTRL1.

2. Specify the input to use (XY_MDS_EAST_WEST bit) by asserting MDS_MAIN.

3. Power on the expected SYSREF buffer by setting XY_MDS_IO_PON_E or XY_MDS_IO_PON_W.

4. Specify optional offset delay by programming register XY_MDS_OFFSET_DLY.

5. Specify the MDS_WIN_LOW and MDS_WIN_HIGH registers.

6. Specify the XY_LMFC_PERIOD.

Other advanced settings could be added, refer to the IDT application note about MDS.

Once the device started (after WCLK and DCLK clocks release), the XY_MDS_LOCK bit could be checked to verify that

MDS process has worked.

SPI MDS init sequence example:

The following SPI sequence shows the list of commands to be used to start the MDS in LMF421 DLQ configuration,

interpolation x2 mode, with PLL on (Fclkin=491.52 MHz Fs=1474.56 MHz). Step 1 to 21 corresponds to standard

initialization of the DAC in above configuration. Step 22 ..31 are useful to start the MDS feature. if MDS test is needed in

other configurationonly step 1..21 need to be rewrite.

11.9 Interrupts

In some cases it may be useful if the host-controller is notified that a certain internal event has taken place by means of an

interrupt. The DAC165xQ includes a simple interrupt (INTR) controller for this purpose.

The INTR-signal can be made available on one of the I/O pins. The polarity is programmable (see section Section 11.9.7).

11.9.1 Events monitored

The DAC165xQ monitors various internal events and indicates their occurrence in the XY_INTR_FLAGS_0 and

XY_INTR_FLAGS_1 registers. The following event can be observed:

•XY_INTR_DLP:

Digital Lane Processing (DLP) has its own interrupt controller. The result of this slave controller is provided to the main

interrupt controller through the XY_INTR_DLP bit.

•XY_MDS_BUSY and XY_MDS_BUSY:

Refer to the activity of the MDS controller. During the synchronization phase, the XY_MDS_BUSY signal is high, and

becomes low once finished.

–XY_MDS_BUSY reflects the start of the activity of the MDS controller

–XY_MDS_BUSY reflects the end of the activity of the MDS controller

•XY_TEMP_ALARM:

Indicates that the temperature measured by the on-chip temperature sensor exceeds the threshold temperature (see

Section 11.7).

•XY_CLIP_DET_OR:

Indicates that one of the level detectors is enabled.

•XY_CA_ERR:

Indicates a DLP clock error.

•XY_CLK_MON:

Indicates a CDI clock error.

•XY_MON_DCLK_ERR:

Indicates a drift on the DCLK as specified by register XY_INTR_MON_DCLK_RANGE.

•XY_ERR_RPT_FLAG:

Indicates the transmission of error reporting via the SYNCB interface.

•XY_MC_ALARM:

Indicates when an auto-mute event occurs (see Section 11.2.4.10).

11.9.2 Enabling interrupts

An indication of an 01 transition of the corresponding monitor- or error indicator activates the INTR-signal can be given

using the XY_INTR_ENA_0 and XY_INTR_ENA_1 registers. The XY_INTR_FLAGS_0 and XY_INTR_FLAGS_1 registers

indicate which of the selected events has invoked the interrupt. When bit XY_INTR_CLEAR is set to 1 the flags and the

INTR-signal are reinitialized.

11.9.3 Digital Lane Processing (DLP) interrupt controller

The DLP has its own interrupt controller that reports to the main interrupt controller. This DLP interrupt controller is

managed from the SPI registers of block x00E0/x02E/0x04E0 (see Figure 66).

XY_INTR_MODE

As this interrupt controller is dedicated to the JESD204B serial interface the XY_INTR_MODE bits must be specified

according to the LMF configuration used in the system.

[1]The lane numbering refers to the logical lanes (see Section 11.9.4).

[2]Any mode can also be used for debug purposes.

[3]The "FLAG_CNT" feature is explained in Section 11.9.6.1.

The DLP events that can be monitored with the interrupt controller are programmable via register XY_INTR_ENA0. Those

events are related to the lanes specified by the XY_INTR_MOD bits register. Interrupt can be enabled by the following bits:

•XY_INTR_ENA_NIT: enables Not-In-Table (NIT) error on one of the lanes

Block 00E0h = DAC A/B

Block 02E0h = DAC C/D

Block 04E0h = All DACs

DAC1653Q/DAC1658Q

Quad 16-bit DAC: 10 Gbps JESD204B interface: x2, x4 and x8 interpolating

Advance data sheet

Because of various implementations for JESD204B transmitter devices, a flexible configuration of the physical lanes is

required. This configuration allows the lane polarity to invert individually and to arbitrary swap the lane order. Identifying the

lane numbers can be confusing because of the lane swapping. Two terms, physical and logical, are used in this document

to explicitly identify the lanes.

Physical lanes:

The DAC165xQ integrates two times four JESD204B serial receivers that are referenced via the pinning information (see

Figure 2).

•DAC A/B physical lane 0 refers to the signal coming from pins VIN_AB_P0 and VIN_AB_N0

•DAC A/B physical lane 1 refers to the signal coming from pins VIN_AB_P1 and VIN_AB_N1

•DAC A/B physical lane 2 refers to the signal coming from pins VIN_AB_P2 and VIN_AB_N2

•DAC A/B physical lane 3 refers to the signal coming from pins VIN_AB_P3 and VIN_AB_N3

•DAC C/D physical lane 0 refers to the signal coming from pins VIN_CD_P0 and VIN_CD_N0

•DAC C/D physical lane 1 refers to the signal coming from pins VIN_CD_P1 and VIN_CD_N1

•DAC C/D physical lane 2 refers to the signal coming from pins VIN_CD_P2 and VIN_CD_N2

•DAC C/D physical lane 3 refers to the signal coming from pins VIN_CD_P3 and VIN_CD_N3

Logical lanes:

The DAC165xQ incorporates a Swap lanes module (see Figure 67) that allows a remapping of the lane numbers to be

compatible with the system implementation.

•DAC A/B logical lane 0 refers to the lane specified with the XY_LANE_SEL_L_LN#0 bits in register

XY_LANE_SELECT (adress = 0x0CE).

•DAC A/B logical lane 1 refers to the lane specified with the XY_LANE_SEL_L_LN#1 bits in register

11.9.5 RX Digital Lane Processing (DLP)

Digital lane processing is the module containing all JESD204B interface controls except the PHY deserializer.

Figure 68 shows the registers for the configuration of the digital lane processing.

11.9.5.1 Lane polarity

Each physical lane polarity can be individually inverted with the XY_POL_P_LN x bits of register XY_LANE_POLARITY.

Using this feature transforms the 10 bits from ABCDEFGHIJ to ABCDEFGHIJ.

11.9.5.2 Scrambling

The descrambler is a 16-bit parallel self-synchronous descrambler based on the polynomial 1 + x14 + x15. From the

JESD204B specification, the scrambling/descrambling process only occurs on the user data, not on the code group

synchronization or the ILA sequence. After two received bytes, the descrambler is correctly set up to decode the data in the

proper way. However, if the initial state of the descrambler bits is set incorrectly, the two first decoded bytes are decoded

incorrectly. The JESD204B specification proposes an initial state for both scrambler and descrambler to avoid this.

Using registers XY_INIT_DESCR_P_LN0 x any kind of intitial state can be set in the DAC165xQ. The descrambling

process starts when the ILA sequence has finished. This process can be turned off by deasserting bit XY_EN_SCR in

The first samples cannot be sent to the DSP using the XY_FORCE_1ST_SMPL_LOW bits of register XY_ALIGN_CNTRL.

This avoids the use of the two incorrectly decoded samples.

11.9.5.3 Lane swapping and selection

If the physical lanes do not match with the ordering of the transmitter lanes, they can be reordered using the lane swapping

module. As the DAC165xQ allows various LMF configurations, it is important that the lane swapping respects the following

reordering constraints linked to the L value (see Table 35).

The selection of the logical lanes can be is specified by the XY_LANE_SEL_L_LN x bits of register XY_LANE_SELECT.

11.9.5.4 Word locking and Code Group Synchronization (CGS)

When the bits are received from the RX physical layer, DLP has to identify the MSB and LSB boundaries of the 10-bit codes

from the bitstream. This can be monitored using the XY_LOCK_CNT_MON_P_LN01 and XY_LOCK_CNT_MON_P_LN23

registers.

When all lanes are locked, the values of the registers are stable and the code group synchronization process can start. This

process is described by the JESD204B specification and is represented by the state machine shown in Figure 69.

The CGS states of each lane can be monitored using the XY_CS_STATE_P_LN x bits of register XY_CS_STATE_P_LNX.

The definition of each state can be found in Table 37.

11.9.5.5 SYNC configuration

The SYNC signal is the feedback signal that is sent to the transmitter device to ensure the JESD204B link synchronization.

When one lane are in CS_INIT state a sync_request is sent to the SYNC buffer.

•in DLQ (Dual Link Quad ) configuration the two internal dual DAC run independently. So two SYNC signals have to be

output by the DAC165xQ device. SYNCB_SELECT_E[1:0] bit of register SRC_SELECT_CNTRL register enables to

select which SYNC signal (from data path AB or from data path CD) will be output on pins SYNCB_E_P/N.

SYNCB_SELECT_W[1:0] bit of register SRC_SELECT_CNTRL register enables to select which SYNC signal (from

data path AB or from data path CD) will be output on pins SYNCB_W_P/N.

•in SLQ (Single Link Quad ) configuration the two internal dual DAC are synchronized together. So only one SYNC

signal need to be output by the DAC165xQ device. as previously this SYNC signal could be output on either pins

SYNCB_E_P/N or pins SYNCB_W_P/N using SRC_SELECT_CNTRL register.

The polarity of SYNC signal is controlled by bit XY_SYNC_POL of register XY_LANE_POLARITY. By default the

synchronization request is active low. The synchronization request signal can be specified by bits XY_SEL_SYNC[2:0] of

the sync_request signal after resetting the CGS state machine (at start-up time or after device reset only). Detail

XY_SEL_SYNC[2:0] configuration is presented in Table 38 .

Quad 16-bit DAC: 10 Gbps JESD204B interface: x2, x4 and x8 interpolating

Advance data sheet

During the ILA sequence, the K28.3 (/A/ symbol) is used to align the data streams. During this sequence, the length (K) of

the multi-frame is measured. This value is used by the lane monitoring and correction process. The value is also used for

the MDS circuitry, where the SYSREF signal is expected to be a multiplication of the multi-frame length (K) in the

JESD204B specification.

During the second multi-frame, the JESD204B configuration data of physical lane 0 is stored in register XY_P_LN0_CFG_0

to XY_P_LN0_CFG_13 (similarly register XY_LNx_CFG_0 to XY_LNx_CFG_13 for lane x ) (see Figure 70). The

DAC165xQ does not do anything with these configuration data. They are only made available for the host controller.

The ILA module uses a 16-bit buffer for each lane. The first /A/ symbol received over the lanes is used as reference. The /A/

symbols of the other lanes, which are received later, are compared to the first one to be all aligned. The initial location of the

symbols is predefined by the XY_INIT_ILA_BUFPTR_L_LN x registers. The alignment can be monitored with the

XY_ILA_MON_L_LN x registers. If the lane difference is too great, a buffer out-of-range error occurs, which can be

monitored with bits XY_ILA_BUF_ERR_L_LN x registers. In this specific case, a reinitialization of the full link can be

requested by setting the XY_REINIT_ILA_L_LN x bits of register XY_REINIT_CNTRL.

The JESD204B specification also mentions a dynamic realignment mode where a monitoring process is checking the

/A/-symbol location. This can realign the data stream if two successive /A/ symbols are found at the same new position. By

default this monitoring and correction process is disabled to avoid any moving latency over the link, but one can enable the

feature by setting the XY_DYN_ALIGN_ENA bit of register XY_ALIGN_CNTRL.

11.9.5.9 Character replacement

Character replacement, as specified by the JESD204B specification, can occur at the end of the frame (K28.7 or /F/

symbol) or at the end of the multi-frame (K28.3 or /A/ symbol). By default this feature is enabled, but it can be disabled

using bit XY_FRAME_ALIGN_ENA of the XY_ALIGN_CNTRL register.

Remark: The DAC165xQ can handle multi-frame length values (K) between ceil(17 / F) and 32 but with the restriction that

the number of octets in a multi-frame must always be even. This implies that if F = 1, a value of K = 17 is not allowed. When

F = 1 only even values > 17 are allowed. Working with F = 1 and K = 17 often implies that the character replacement

process is not reliable.

11.9.5.10 Sample assembly

Sample assembly handles the assembly of the data based on the LMF parameters described by register XY_LMF_CNTRL.

each dual DAC of DAC165xQ need to be programmed independently. this means that if LMF841 is targeted ,in fact each

dual DAC instance need to be programmed in LMF421 and in parallel SLQ (Single Link Quad) mode need to be

selected.The following configurations are supported:

•LMF-S = 421-1

•LMF-S = 422-2

•LMF-S = 222-1

•LMF-S = 124-1

Sample assembly is based on the logical lanes definition when updating the L value.

11.9.5.11 Resynchronization over links

The DAC165xQ recognizes a K28.5 (/K/) symbols sequence coming over its lanes. This identification allows

resynchronization of the device if the XY_RESYNC_OLINK_P_LN x bits of register XY_REINIT_CNTRL are set correctly.

11.9.5.12 Symbols detection monitoring and error handling

The DLP decodes the 10-bit words to 8-bit words. The decoding table is specified in the IEEE 802.3-2005 specification.

During decoding, the disparity is calculated according to the disparity rules mentioned in the same specification. The

JESD204B specification also defines the following definitions:

•VALID:

The code group is found in the column of the 10b/8b decoding tables according to the current running disparity.

•DISPARITY ERROR:

The received code group exists in the 10b/8b decoding table, but is not found in the correct column according to the

current running disparity.

•NOT-IN-TABLE (NIT) ERROR:

The received code group is not found in the 10b/8b decoding table of either disparity.

•INVALID:

A code group that either shows a disparity error or that does not exist in the 10b/8b decoding table.

Remark: The 8b/10b decoder only provides reliable information in the CSYNC_CHCK and CSYNC_DATA states. During

CSYNC_INIT state, the DLP is "hunting" for the correct position of the K28.5 (/K/) symbols in the received bitstream.

Therefore the DISPARITY ERROR/NOT-IN-TABLE/ INVALID flags are not yet consistent and are not be used in the

internal monitoring.

Quad 16-bit DAC: 10 Gbps JESD204B interface: x2, x4 and x8 interpolating

Advance data sheet

The Not-In-Table error (NIT) and Disparity error (DISP) can be monitored using the DEC_NIT_ERR_P_LNx_XY and

XY_DEC_DISP_ERR_P_LN x bits of register XY_DEC_FLAGS. Both are considered invalid, but the DAC165xQ has some

flexibility in this definition. The specified invalid errors can also be totally ignored by setting the bit XY_ IGNORE_ERR of

measurement needs to be executed.

The VALID/INVALID status of the decoded word can trigger the MUTE feature using the XY_IGNORE_DATA_V_IQ bits of

The following comma symbols are detected during data transmission irrespective of the running disparity:

/K/ = K28.5

/F/ = K28.7

/A/ = K28.3

/R/ = K28.0

/Q/ = K28.4

Their single detection is monitored in registers XY_KOUT_FLAG and XY_K28_LN x _FLAG.

During the data transmission phase, only K28.3 (/A/) and K28.7 (/F/) symbols are expected. Sometimes (e.g. wrong bit

transmission), a code group is interpreted as a K character that is not K28.3 or K28.7. If this occurs a KOUT_UNEXP flag is

asserted that can be read using the XY_DEC_KOUT_UNEXP_LN x bits of register XY_KOUT_UNEXPECTED_FLAG.

All the previous flags can be reset using the XY_MON_FLAGS_RESET register. Detection of them can also assert the DLP

interrupt (see Section 11.9.3).

11.9.6 Monitoring and test modes

The DAC165xQ embeds various monitoring and test modes that are useful during the prototyping phase of a system.

Remark: The test capability linked to observing specific characters, errors or state machine statuses is not reviewed in this

section. It is up to the reader to define specific modes based on the DAC165xQ capability.

11.9.6.1 Flag counters

Due to the high data rate of the JESD204B serial interface, it is hard to monitor events that occur on the lanes in real time.

Four multi-purpose counters have been added to the design to help this monitoring. Each counter is 16 bits wide and is

linked to one lane. It increments its value each time a specific event occurs. These flags counters can be read using the

XY_FLAG_CNT_LSB_LN x and XY_FLAG_CNT_MSB_LN x registers and reset using the XY_CNTRL_FLAGCNT_LN x

registers. The flag counters can also be reset automatically when DLP is reset by setting the XY_AUTO_RST_FLAGCNTS

bit of register XY_MISC_FLAG_CNTRL to logic 1.

The specification of the event that increments the counter is done by setting the XY_SEL_CFC_LN x bits of the

XY_CNTRL_FLAGCNT_LN x registers to one of the sources described in Table 42.

Table 42. Counter source

Default settings are shown highlighted.

Advance data sheet

When the counter is reaching its maximum value (0xFFFF), this value is held until the next counter reset. Bit

XY_FLAGCNT_HOLD_MODE of XY_MISC_FLAG_CNTRL register gives two options for when a counter reaches the

maximum value.

When the counters are stopped, an interrupt can be activated (see Section 11.9.3).

This feature makes it possible to, for instance, analyze the occurrence of character replacement or NIT errors.

11.9.6.2 Sample Error Rate (SER)

A sample error rate feature is implemented in the DAC165xQ to analyze the quality of the transmission. Due to the 8b10b

encoding, the analysis is done at sample level only and not at bit level. The transmitter sends a constant data over the link

and the DAC165xQ compared this received value to the value specified in the XY_BER_LEVEL_P_LN x[15:0] registers.

Enable the scrambling on both transmitter and receiver side to add more random effect on the data. The

XY_BER_LEVEL_P_LN x[15:0] are specifying a 16-bit value at the lane level, it means the device can be considered as

operating in one of two modes:

•F = 2 mode:

The lane is receiving 16-bit data specified by this register.

•F = 1 mode:

The lane is receiving alternately 8-bit data specified by MSB and LSB of this register.

The SER mode requires that the DAC is already synchronized (using CGS and ILA sequence). The kick-off of the

measurement is done by setting the XY_BER_MOD bit of register XY_DBG_CNTRL. In this mode, the flags counters are

used to count the number of 16-bit samples that do not match the XY_BER_LEVEL_P_LN x value. This mode enables the

establishing of the sample error rate of each lane.

11.9.6.3 PRBS test

The DAC165xQ embeds PRBS7,PRBS15, PRBS23, and PRBS31 PRBS checkers that are shared for the 4 lanes of each

dual DAC.

To test a specific lane, the setting XY_SEL_XBERT_LN[1:0] needs to be set first. Then it is required to disable the restart of

the RX PHY due to the error monitoring this is done by setting the register XY_IGNORE_ERR[1:0] to value 3 and

XY_REINIT_CNTRL to value x00. After the release of the DCLK and WCLK clocks, the XY_XBERT_CNTRL[2:0] bits must

specified to the expected test (PRBS31, 23 , 15, 7) and the XY_CHECK_PRBS bit must be set to the “sync to prbs

sequence” mode. Once synchronized, the internal PRBS counter is aligned with the received PRBS sequence. The test

starts when the XY_CHECK_PRBS is set to 1 (ie= “check PRBS sequence” mode). The XY_XBERT_CNT[15:0] counter

11.9.6.4 JTSPAT test

The Jitter Tolerance Scrambled PATtern (JTSPAT) is an 1180-bit pattern intended for receiving jitter tolerance testing for

scrambled systems. The JTSPAT test pattern consists of two copies of JSPAT and an additional 18 characters intended to

cause extreme late and early phases in the CDR PLL followed by a sequence, which can cause an error (i.e. an isolated bit

following a long run). This pattern was developed to stress the receiver within the boundary conditions established by

scrambling.

Advance data sheet

[1] This table must be read, starting from the top, left-to-right first and then line-by-line to follow the sequence.

The DAC165xQ embeds a JTSPAT checker. JTSPAT checker is start in same way than PRBS test using

XY_XBERT_CNTRL[2:0]=001.

11.9.6.5 DLP strobe

The data coming out of the ILA module can be sampled by setting the XY_DLPSTROBE bit of register XY_MISC_CNTRL.

On each lane two octets are stored, which can be read out through bit XY_LN10_SAMPLE[15:0] (in register

XY_LN10_SAMPLE_LSB and XY_LN10_SAMPLE_MSB) and XY_LN32_SAMPLE[15:0] (in register

XY_LN32_SAMPLE_LSB and XY_LN32_SAMPLE_MSB). The selection of the lane to read out the data is done by

registers XY_LN10_SEL and XY_LN32_SEL.

11.9.7 IO-mux

The DAC165xQ uses four general purpose pins, IO0 IO1, IO2 and IO3. IOs can be configured as an input (x01) or as an

output (x00) by setting the IO_ENA bit of register IO_CNTRL.

When acting as an input, the IO1 pin is referred as the RF enable feature (see Section 11.2.6).

When acting as an output, the two IO pins are multiplexed to internal signals that can be useful for debug purposes.

Table 46 shows the main configuration when using registers bit IO_SELECT_ x in register IO_MUX_CNTRL x. The

definitions of the three registers depend on the "Indicator" and the "Range" values used to specify the signal that is sent

through the IOs pins (see Table 46 and Table 47).

Each JESD204B lane owns its own physical de-serializer (RX PHY) that provides the 10-bit data stream to the DLP

module. The DAC165xQ provide various control features of the RX PHY, like the equalizer, the common-mode voltage and

the resistor termination.

Remark: Most of the main controls (power on/off, PLL clock dividers, etc.) are automatically set while specifying the LMF

11.10.1 Lane input

Each lane is Current Mode Logic (CML) compliant.

Rx lanes need to be connected to FPGA Tx using AC-coupling. The DAC165xQ do not need on PCB external termination:

lane’s terminations are already included.

11.10.2 Equalizer

The lane 0 of DAC165xQ embeds an internal equalizer controlled by bits XY_HS_RX_0_EQ_IF_GAIN[2:0] (similarly, bits

XY_HS_RX_n_EQ_IF_GAIN[2:0] controls lane n). This improves the interference robustness between signals by

amplifying the high-frequency jumps in the data conserving the energy of the low-frequencies ones. The equalizer can be

programmed depending on the quality of the channel used (PCB traces/layout, connectors, etc.). The total Equalizer gain is

defined in Table 48 and Figure 72.

•

The auto-zero feature (bit XY_HS_RX_EQ_AUTO_ZERO_ENABLE in register XY_HS_RX_EQ_CNTRL) is enabled by

default for the deserializer to adapt itself to the common-mode of the received signal.

11.10.3 Deserializer

The deserializer performs the incoming data clock recovery and also the serial-to-parallel conversion. One global PLL

provides the same reference clock to the four lanes. The PLL configuration is automatically done when specifying the LMF

parameters (see Table 10).

11.10.4 Low Serial Input Data Rate

When using the DAC165xQ with a low serial input data rate (lower than 3 Gbps), it is recommended to enable the low

speed mode of the Clock Data Recovery (CDR) unit by writing the value x84 in register XY_HS_RX_CDR_DIV.

A special test mode is available for measurement purposes only. The recovered clock of each CDR unit can be transmitted

to the SYNC buffer after a frequency division by 20. This is done by setting the XY_SYNC_TEST_DATA_TX_ENABLE bit

of register XY_SYNC_SEL_CNTRL_XY to logic 1. Bit XY_SYNC_TEST_DATA_SEL[1:0] is used to specify which CDR

11.12 Design recommendations : power and grounding

Use a separate LDO power supply regulator for the generation of the VDDA(1V2) and VDDD(1V2) to ensure optimal

performance.

VDDJ_SO (JESD204B SYNCB power supply) , VDDD_IO (IO interface power supply) , VDDD(1V2) (Digital core power supply),

and VDDj(1V2) (JESD204B lane power supply) can use dedicated or shared power supply. LDO or switch power supply for

these power supplies.

Use Low noise power supply for the generation of VDDA(1V2) , VDDA(out) power supplies in order to ensure optimal

performance.

Include individual LC decoupling for the following nine sets of power pins:

•VDDA(1V2)_DAC_AB (pins 65, 68, 69, 72)

•VDDA(1V2)_DAC_CD (pins 55, 58, 59, 62)

•VDDA(1V2)_BIASING (pins 50, 53)

•VDDA(1V2)_CLOCK (pins 2)

•VDDD(1V2) (pins 8, 15, 40, 47) , VDDD_IO (pin 41) and VDDJ_SO (pin 39)

•VDDJ(1V2) (pins 16, 23, 32)

•VDDA(out)_AB (pins 1, 64)

VDDA(out)_CD (pins 54, 63)

•VDDA(out)_pll (pins 5)

Use at least two capacitors for each power pin decoupling. Locate the smallest capacitors as

close as possible to the DAC165xx power pins.

The die pad is used for both the power dissipation and electrical grounding. Insert several vias (typically 4*12 to connect the

internal ground plane to the PCB top layer.

14. GLOSSARY

14.1 Static parameters

INL. The deviation of the transfer function from a best fit straight line (linear regression computation).

DNL. The difference between the ideal and the measured output value between successive DAC codes.

14.2 Dynamic parameters

Spurious-Free Dynamic Range (SFDR). The ratio between the RMS value of the reconstructed output sine wave and the

RMS value of the largest spurious observed (harmonic and non-harmonic, excluding DC component) in the frequency

domain.

InterModulation Distortion (IMD). From a dual-tone digital input sine wave (these two frequencies being close together),

the intermodulation distortion products IMD2 and IMD3 (second order and third order components) are defined below.

IMD2. The ratio between the RMS value of either tone and the RMS value of the worst second order intermodulation

product.

IMD3. The ratio between the RMS value of either tone and the RMS value of the worst third order intermodulation product.

Total Harmonic Distortion (THD). The ratio between the RMS value of the harmonics of the output frequency and the

RMS value of the output sine wave. Usually, the calculation of THD is done on the first 5 harmonics.

Signal-to-Noise Ratio (SNR). The ratio between the RMS value of the reconstructed output sine wave and the RMS value

of the noise excluding the harmonics and the DC component.

Restricted BandWidth Spurious-Free Dynamic Range (SFDRRBW). the ratio between the RMS value of the

reconstructed output sine wave and the RMS value of the noise, including the harmonics, in a given bandwidth centered

around foffset.
