The product operates at up to a 250 MSPS conversion rate and is optimized for outstanding dynamic performance in wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and voltage reference, are included on the chip to provide a complete signal conversion solution. 1. High Performance--Maintains 59.4 dBFS SNR @ 250 MSPS with a 70 MHz input. 2. Low Power--Consumes only 322 mW @ 250 MSPS. 3. Ease of Use--CMOS output data and output clock signal allow interface to current FPGA technology. The on-chip reference and sample-and-hold provide flexibility in system design. Use of a single 1.8 V supply simplifies system power supply design. 4. Serial Port Control--Standard serial port interface supports various product functions, such as data formatting, powerdown, gain adjust, and output test pattern generation. 5. Pin-Compatible Family--12-bit pin-compatible family offered as the AD9626. The ADC requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are CMOS compatible and support either twos complement, offset binary format, or Gray code. A data clock output is available for proper output data timing. Fabricated on an advanced CMOS process, the AD9601 is available in a 56-lead LFCSP, specified over the industrial temperature range (-40C to +85C).

This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL RESISTANCE The exposed paddle must be soldered to the ground plane for the LFCSP package. Soldering the exposed paddle to the customer board increases the reliability of the solder joints, maximizing the thermal capability of the package. Table 6. Package Type 56-Lead LFCSP (CP-56-2) JA 30.4 JC 2.9 Unit C/W Typical JA and JC are specified for a 4-layer board in still air. Airflow increases heat dissipation, effectively reducing JA. In addition, metal in direct contact with the package leads from metal traces, and through holes, ground, and power planes reduces the JA. 150C ESD CAUTION Rev. 0 | Page 8 of 32 AD9601 56 55 54 53 52 51 50 49 48 47 46 45 44 43 DA3 DA2 DA1 DA0 (LSB) NIC NIC DCO+ DCO- DRGND DRVDD AVDD CLK- CLK+ AVDD PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 PIN 1 INDICATOR AD9601 TOP VIEW (Not to Scale) PIN 0 (EXPOSED PADDLE) = AGND 42 41 40 39 38 37 36 35 34 33 32 31 30 29 AVDD AVDD CML AVDD AVDD AVDD VIN- VIN+ AVDD AVDD AVDD RBIAS AVDD PWDN 07100-002 DB3 DB4 DB5 DB6 DB7 DB8 (MSB) DB9 OVRB DRGND DRVDD SDIO/DCS SCLK/DFS CSB RESET 15 16 17 18 19 20 21 22 23 24 25 26 27 28 DA4 DA5 DA6 DA7 DA8 (MSB) DA9 DRVDD DRGND OVRA NIC NIC (LSB) DB0 DB1 DB2 Figure 4.

This internal voltage reference can be adjusted by means of SPI control. See the AD9601 Configuration Using the SPI section for more details. AD8138 523 VIN- 33 CML 499 Figure 33. Differential Input Configuration Using the AD8138 At input frequencies in the second Nyquist zone and above, the performance of most amplifiers may not be adequate to achieve the true performance of the AD9601. This is especially true in IF undersampling applications where frequencies in the 70 MHz to 100 MHz range are being sampled. For these applications, differential transformer coupling is the recommended input configuration. The signal characteristics must be considered when selecting a transformer. Most RF transformers saturate at frequencies below a few millihertz, and excessive signal power can also cause core saturation, which leads to distortion. In any configuration, the value of the shunt capacitor, C, is dependent on the input frequency and may need to be reduced or removed. 15 1.25V p-p 50 VIN+ AD9601 2pF VIN- 15 0.1F Figure 34.

For baseband applications, the AD8138 differential driver provides excellent performance and a flexible interface to the ADC. The output common-mode voltage of the AD8138 is easily set to AVDD/2 + 0.5 V, and the driver can be configured in a Sallen-Key filter topology to provide band limiting of the input signal. AD9601 20pF 0.1F The analog input to the AD9601 is a differential buffer. For best dynamic performance, the source impedances driving VIN+ and VIN- should be matched such that common-mode settling errors are symmetrical. The analog input is optimized to provide superior wideband performance and requires that the analog inputs be driven differentially. A wideband transformer, such as Mini-Circuits(R) ADT1-1WT, can provide the differential analog inputs for applications that require a single-ended-to-differential conversion. Both analog inputs are self-biased by an on-chip resistor divider to a nominal 1.4 V.

Differential Input Configuration Using the AD8352 07100-010 The input stage contains a differential SHA that can be ac- or dc-coupled. The output-staging block aligns the data, carries out the error correction, and passes the data to the output buffers. The output buffers are powered from a separate supply, allowing adjustment of the output voltage swing. During powerdown, the output buffers go into a high impedance state. 49.9 07100-008 Each stage of the pipeline, excluding the last, consists of a low resolution flash ADC connected to a switched capacitor DAC and interstage residue amplifier (MDAC). The residue amplifier magnifies the difference between the reconstructed DAC output and the flash input for the next stage in the pipeline. One bit of redundancy is used in each stage to facilitate digital correction of flash errors. The last stage simply consists of a flash ADC. 1V p-p 07100-009 The AD9601 architecture consists of a front-end sample-andhold amplifier (SHA) followed by a pipelined switched capacitor ADC. The quantized outputs from each stage are combined into a final 10-bit result in the digital correction logic. The pipelined architecture permits the first stage to operate on a new input sample, while the remaining stages operate on preceding samples. Sampling occurs on the rising edge of the clock. AD9601 For optimum performance, the AD9601 sample clock inputs (CLK+ and CLK-) should be clocked with a differential signal. This signal is typically ac-coupled into the CLK+ pin and the CLK- pin via a transformer or capacitors. These pins are biased internally and require no additional bias. Figure 36 shows one preferred method for clocking the AD9601. The low jitter clock source is converted from single-ended to differential using an RF transformer. The back-to-back Schottky diodes across the secondary transformer limit clock excursions into the AD9601 to approximately 0.8 V p-p differential. This helps prevent the large voltage swings of the clock from feeding through to other portions of the AD9601 and preserves the fast rise and fall times of the signal, which are critical to low jitter performance.

In such applications, CLK+ should be directly driven from a CMOS gate, and the CLK- pin should be bypassed to ground with a 0.1 F capacitor in parallel with a 39 k resistor (see Figure 39). Although the CLK+ input circuit supply is AVDD (1.8 V), this input is designed to withstand input voltages up to 3.3 V, making the selection of the drive logic voltage very flexible. 07100-014 CLOCK INPUT CONSIDERATIONS Typical high speed ADCs use both clock edges to generate a variety of internal timing signals. As a result, these ADCs may be sensitive to the clock duty cycle. Commonly, a 5% tolerance is required on the clock duty cycle to maintain dynamic performance characteristics. The AD9601 contains a duty cycle stabilizer (DCS) that retimes the nonsampling edge, providing an internal clock signal with a nominal 50% duty cycle. This allows a wide range of clock input duty cycles without affecting the performance of the AD9601. When the DCS is on, noise and distortion performance are nearly flat for a wide range of duty cycles. However, some applications may require the DCS function to be off. If so, keep in mind that the dynamic range performance can be affected when operated in this mode. See the AD9601 Configuration Using the SPI section for more details on using this feature. The duty cycle stabilizer uses a delay-locked loop (DLL) to create the nonsampling edge. As a result, any changes to the sampling frequency require approximately eight clock cycles to allow the DLL to acquire and lock to the new rate. Rev. 0 | Page 17 of 32 AD9601 Clock Jitter Considerations High speed, high resolution ADCs are sensitive to the quality of the clock input. The degradation in SNR for a full-scale input signal at a given input frequency (fA) due only to aperture jitter (tJ) can be calculated by SNR Degradation = 20 x log10[1/2 x x fA x tJ] In this equation, the rms aperture jitter represents the root mean square of all jitter sources, including the clock input, analog input signal, and ADC aperture jitter specifications. IF undersampling applications are particularly sensitive to jitter (see Figure 41). The clock input should be treated as an analog signal in cases where aperture jitter may affect the dynamic range of the AD9601. Power supplies for clock drivers should be separated from the ADC output driver supplies to avoid modulating the clock signal with digital noise. Low jitter, crystal controlled oscillators make the best clock sources. If the clock is generated from another type of source (by gating, dividing, or other methods), it should be retimed by the original clock at the last step. Refer to the AN-501 Application Note and the AN-756 Application Note for more in-depth information about jitter performance as it relates to ADCs (visit www.analog.com). 130 RMS CLOCK JITTER REQUIREMENT 90 14 BITS The off-chip drivers on the AD9601 are CMOS-compatible output levels. The outputs are biased from a separate supply (DRVDD), allowing isolation from the analog supply and easy interface to external logic. The outputs are CMOS devices that swing from ground to DRVDD (with no dc load). It is recommended to minimize the capacitive load the ADC drives by keeping the output traces short (<1 inch, for a total CLOAD < 5 pF). When operating in CMOS mode, it is also recommended to place low value (20 ) series damping resistors on the data lines to reduce switching transient effects on performance. The format of the output data is offset binary by default. An example of the output coding format can be found in Table 11. If it is desired to change the output data format to twos complement, see the AD9601 Configuration Using the SPI section. 12 BITS 70 10 BITS 60 8 BITS 50 40 1 0.125ps 0.25ps 0.5ps 1.0ps 2.0ps 10 100 ANALOG INPUT FREQUENCY (MHz) 1000 Figure 41. Ideal SNR vs. Input Frequency and Jitter for 0 dBFS Input Signal POWER DISSIPATION AND POWER-DOWN MODE As shown in Figure 28, the power dissipated by the AD9601 is proportional to its sample rate. The digital power dissipation does not vary much because it is determined primarily by the DRVDD supply and bias current of the LVDS output drivers. An out-of-range condition exists when the analog input voltage is beyond the input range of the ADC. OVRA/OVRB is a digital output that is updated along with the data output corresponding to the particular sampled input voltage. Thus, OVRA/OVRB has the same pipeline latency as the digital data. OVRA/OVRB is low when the analog input voltage is within the analog input range and high when the analog input voltage exceeds the input range, as shown in Figure 42. OVRA/OVRB remains high until the analog input returns to within the input range and another conversion is completed. By logically AND-ing OVRA/OVRB with the MSB and its complement, overrange high or underrange low conditions can be detected. By asserting PDWN (Pin 29) high, the AD9601 is placed in standby mode or full power-down mode, as determined by the contents of Serial Port Register 08. Reasserting the PDWN pin low returns the AD9601 into its normal operational mode. An additional standby mode is supported by means of varying the clock input. When the clock rate falls below 20 MHz, the AD9601 assumes a standby state. In this case, the biasing network Rev. 0 | Page 18 of 32 OVRA/OVRB DATA OUTPUTS 1 0 0 1111 1111 1111 1111 1111 1111 1111 1111 1110 +FS - 1 LSB OVRA/ OVRB -FS + 1/2 LSB 0 0 1 0000 0000 0001 0000 0000 0000 0000 0000 0000 -FS -FS - 1/2 LSB +FS +FS - 1/2 LSB 07100-017 80 30 Digital Outputs and Timing Out-of-Range 07100-016 SNR (dB) 110 16 BITS DIGITAL OUTPUTS An output clock signal is provided to assist in capturing data from the AD9601. The DCO+/DCO- signal is used to clock the output data and is equal to the sampling clock (CLK) rate in single port mode, and one-half the clock rate in interleaved output mode. See the timing diagrams shown in Figure 2 and Figure 3 for more information. 120 100 and internal reference remain on, but digital circuitry is powered down. Upon reactivating the clock, the AD9601 resumes normal operation after allowing for the pipeline latency. Figure 42. OVRA/OVRB Relation to Input Voltage and Output Data AD9601 TIMING--SINGLE PORT MODE In single port mode, the CMOS output data is available from Data Port A (DA0 to DA9). The outputs for Port B (DB0 to DB9) are unused, and are high impedance in this mode. The Port A outputs and the differential output data clock (DCO+/DCO-) switch nearly simultaneously during the rising edge of DCO+. In this mode, it is recommended to use the rising edge of DCO- to capture the data from Port A. The setup and hold time depends on the input sample clock period, and is approximately 1/fCLK tSKEW. TIMING--INTERLEAVED MODE In interleaved mode, the output data of the AD9601 is demultiplexed onto two data port buses, Port A (DA0 to DA9) and Port B (DB0 to DB9). The output data and differential data capture clock switch at one-half the rate of the sample clock input (CLK+/CLK-), increasing the setup and hold time for the external data capture circuit relative to single port mode (see Figure 3, interleaved mode timing diagram). The two ports switch on alternating sample clock cycles, with the data for Port A being valid during the rising edge of DCO+, and the data for Port B being valid during the rising edge of DCO-. The pipeline latency for both ports is six sample clock cycles. Due to the random nature of the /2 circuit that generates the timing for the output stage in interleaved mode, the first data sample during power-up can be assigned to either Data Port A or Port B. The user cannot control the polarity of the output data clock relative to the input sample clock. In this mode, it is recom- mended to use the rising edge of DCO+ to capture the data from Port A, and the rising edge of DCO- to capture the data from Port B. In both cases, the setup and hold time depends on the input sample clock period, and both are approximately 2/fS tSKEW. fS/2 Spurious Because the AD9601 output data rate is at one-half the sampling frequency in interleaved output mode, there is significant fS/2 energy in the outputs of the part, and there is significant energy in the ADC output spectrum at fS/2. Care must be taken to be certain that this fS/2 energy does not couple into either the clock circuit or the analog inputs of the AD9601. When fS/2 energy is coupled in this fashion, it appears as a spurious tone reflected around fS/4, 3fS/4, 5fS/4, and so on. For example, in a 125 MSPS sampling application with a 90 MHz single-tone analog input, this energy generates a tone at 97.5 MHz. [(3 x 125 MSPS/4 - 90 MHz) + 3 x 125 MSPS/4] Depending on the relationship of the IF frequency to the center of the Nyquist zone, this spurious tone may or may not be in the user's band of interest. Some residual fS/2 energy is present in the AD9601, and the level of this spur is typically below the level of the harmonics at clock rates. Figure 20 shows a plot of the fS/2 spur level vs. the analog input frequency for the AD9601-250. For the specifications provided in Table 2, the fS/2 spur effect is not a factor, as the device is specified in single port output mode. Rev. 0 | Page 19 of 32 AD9601 LAYOUT CONSIDERATIONS POWER AND GROUND RECOMMENDATIONS RBIAS When connecting power to the AD9601, it is recommended that two separate supplies be used: one for analog (AVDD, 1.8 V nominal) and one for digital (DRVDD, 1.8 V nominal). If only a single 1.8 V supply is available, it is routed to AVDD first, then tapped off and isolated with a ferrite bead or filter choke with decoupling capacitors proceeding connection to DRVDD. The user can employ several different decoupling capacitors to cover both high and low frequencies. These should be located close to the point of entry at the PC board level and close to the parts with minimal trace length. The AD9601 requires the user to place a 10 k resistor between the RBIAS pin and ground. This resistor sets the master current reference of the ADC core and should have at least a 1% tolerance. A single PC board ground plane is sufficient when using the AD9601. With proper decoupling and smart partitioning of analog, digital, and clock sections of the PC board, optimum performance is easily achieved. Exposed Paddle Thermal Heat Slug Recommendations It is required that the exposed paddle on the underside of the ADC be connected to analog ground (AGND) to achieve the best electrical and thermal performance of the AD9601. An exposed, continuous copper plane on the PCB should mate to the AD9601 exposed paddle, Pin 0. The copper plane should have several vias to achieve the lowest possible resistive thermal path for heat dissipation to flow through the bottom of the PCB. These vias should be solder-filled or plugged. To maximize the coverage and adhesion between the ADC and PCB, partition the continuous plane by overlaying a silkscreen on the PCB into several uniform sections. This provides several tie points between the two during the reflow process. Using one continuous plane with no partitions guarantees only one tie point between the ADC and PCB. See Figure 43 for a PCB layout example.

Typical PCB Layout CML The CML pin should be decoupled to ground with a 0.1 F capacitor, as shown in Figure 45. AD9601 CONFIGURATION USING THE SPI The AD9601 SPI allows the user to configure the converter for specific functions or operations through a structured register space inside the ADC. This gives the user added flexibility to customize device operation depending on the application. Addresses are accessed (programmed or read back) serially in one-byte words. Each byte can be further divided down into fields, which are documented in the Memory Map section. There are three pins that define the serial port interface or SPI to this particular ADC. They are the SPI SCLK/DFS, SPI SDIO/DCS, and CSB pins. The SCLK/DFS (serial clock) is used to synchronize the read and write data presented the ADC. The SDIO/DCS (serial data input/output) is a dual-purpose pin that allows data to be sent and read from the internal ADC memory map registers. The CSB is an active low control that enables or disables the read and write cycles (see Table 8). Table 8. Serial Port Pins Mnemonic SCLK SDIO CSB RESET Function SCLK (Serial Clock) is the serial shift clock in. SCLK is used to synchronize serial interface reads and writes. SDIO (Serial Data Input/Output) is a dual-purpose pin. The typical role for this pin is an input and output depending on the instruction being sent and the relative position in the timing frame. CSB (Chip Select Bar) is an active low control that gates the read and write cycles. Master Device Reset. When asserted, device assumes default settings. Active low. The falling edge of the CSB, in conjunction with the rising edge of the SCLK, determines the start of the framing. An example of the serial timing and its definitions can be found in Figure 44 and Table 10. During an instruction phase, a 16-bit instruction is transmitted. Data then follows the instruction phase and is determined by the W0 and W1 bits, which is 1 or more bytes of data. All data is composed of 8-bit words. The first bit of each individual byte of serial data indicates whether this is a read or write command. This allows the serial data input/output (SDIO) pin to change direction from an input to an output. Data can be sent in MSB or in LSB first mode. MSB first is default on power-up and can be changed by changing the configuration register. For more information about this feature and others, see Interfacing to High Speed ADCs via SPI at www.analog.com. Rev. 0 | Page 20 of 32 AD9601 HARDWARE INTERFACE CONFIGURATION WITHOUT THE SPI The pins described in Table 8 comprise the physical interface between the user's programming device and the serial port of the AD9601. All serial pins are inputs, which is an open-drain output and should be tied to an external pull-up or pull-down resistor (suggested value of 10 k). In applications that do not interface to the SPI control registers, the SPI SDIO/DCS and SPI SCLK/DFS pins can alternately serve as standalone CMOS-compatible control pins. When the device is powered up, it is assumed that the user intends to use the pins as static control lines for the duty cycle stabilizer. In this mode, the SPI CSB chip select should be connected to ground, which disables the serial port interface. This interface is flexible enough to be controlled by either PROMS or PIC microcontrollers as well. This provides the user with an alternate method to program the ADC other than a SPI controller. Table 9. Mode Selection Mnemonic SPI SDIO/DCS If the user chooses not to use the SPI interface, some pins serve a dual function and are associated with a specific function when strapped externally to AVDD or ground during device poweron.

The memory map is roughly divided into three sections: chip configuration register map (Address 0x00 to Address 0x02), transfer register map (Address 0xFF), and program register map (Address 0x08 to Address 0x2A). Undefined memory locations should not be written to other than their default values suggested in this data sheet. Addresses that have values marked as 0 should be considered reserved and have a 0 written into their registers during power-up. The Addr (Hex) column of the memory map indicates the register address in hexadecimal, and the Default Value (Hex) column shows the default hexadecimal value that is already written into the register. The Bit 7 (MSB) column is the start of the default hexadecimal value given. For example, Hexadecimal Address 0x09, clock, has a hexadecimal default value of 0x01. This means Bit 7 = 0, Bit 6 = 0, Bit 5 = 0, Bit 4 = 0, Bit 3 = 0, Bit 2 = 0, Bit 1 = 0, and Bit 0 = 1, or 0000 0001 in binary. The default value enables the duty cycle stabilizer. Overwriting this default so that Bit 0 = 0 disables the duty cycle stabilizer. For more information on this and other functions, consult the Interfacing to High Speed ADCs via SPI user manual at www.analog.com. Coming out of reset, critical registers are preloaded with default values. These values are indicated in Table 12. Other registers do not have default values and retain the previous value when exiting reset. DEFAULT VALUES LOGIC LEVELS An explanation of various registers follows: "Bit is set" is synonymous with "bit is set to Logic 1" or "writing Logic 1 for the bit." Similarly, "clear a bit" is synonymous with "bit is set to Logic 0" or "writing Logic 0 for the bit." Table 12.
