GENERAL DESCRIPTION
The ADATE304 is a complete, single-chip solution that performs
the pin electronic functions of the driver, the comparator, and
the active load (DCL), per pin PMU, and dc levels for ATE appli-
cations. The device also contains an HVOUT driver with a VHH
buffer capable of generating up to 13.5 V.
The driver features three active states: data high mode, data low
mode, and term mode, as well as an inhibit state. The inhibit
state, in conjunction with the integrated dynamic clamp, facili-
tates the implementation of a high speed active termination.
The ADATE304 supports two output voltage ranges: −2.0 V
to +6.0 V and −1.25 V to +6.75 V by adjusting the positive and
negative supply voltages.
Each channel of the ADATE304 features a high speed window
comparator per pin for functional testing, as well as a per pin
PMU with FV, or FI and MV, or MI functions. All necessary dc
levels for DCL functions are generated by on-chip 14-bit DACs.
The per pin PMU features an on-chip 16-bit DAC for high
accuracy and contains integrated range resistors to minimize
external component counts.
The ADATE304 uses a serial bus to program all functional blocks
and has an on-board temperature sensor for monitoring the
device temperature.

DEFINITION OF SPI WORD
The SPI can accept variable length words, depending on the
operation. At most, the word length equals 24 bits: 16 bits of
data, two channel selects, one read/write (R/W) selector, and a
5-bit address.
Depending on the operation, the data can be smaller or, in the
case of a read operation, nonexistent.
Table 18. Channel Selection
Channel 1 Channel 0 Channel Selected
0 0 NOP (no channel selected, no register
changes)
0 1 Channel 0 selected
1 0 Channel 1 selected
1 1 Channel 0 and Channel 1 selected
Table 19. R/W Definition
R/W Description
0 Current register specified by address shifts out of
SDOUT on next shift operation
1 Current data written to the register specified by
address and channel select
Example 1: 16-Bit Write
Write 16 bits of data to a register or DAC; ignore unused MSBs. For example, Bit 15 and Bit 14 are ignored, and Bit 13 through Bit 0 are
applied to the 14-bit DAC.

READ OPERATION
The read operation is a two-stage operation. First, a word is
shifted in, specifying which register to read. CS is deasserted
for three clock cycles, and then a second word is shifted in to
obtain the readback data. This second word can be either
another operation or an NOP address. If another operation is
shifted in, it must shift in at least eight bits of data to read back
the previous specified data. The NOP address can be used for
this read if there is no need to read/write another register. To
maintain the clarity of the operation, it is strongly recommended
that the NOP address be used for all reads.
Any register read that is fewer than 16 bits has zeros filled in the
top bits to make it a 16-bit word.

RESET OPERATION
The ADATE304 contains an asynchronous reset feature. The
ADATE304 can be reset to the default values shown in Table 2 0
by utilizing the RST pin. To initiate the reset operation, deassert
the RST pin for a minimum of 100 ns and deassert the CS pin
for a minimum of two SCLK cycles.

USER INFORMATION
POWER SUPPLY CONSIDERATIONS
Power Supply Sequencing
It is recommended that the power supplies be brought up in the
following order:
1. Grounds (DGND, AGND, VREF_GND)
2. VSS
3. VCC, VCOMP_VTT, and VREF
4. VDD
5. VPLUS
If the HVOUT pin is not used, the VPLUS supply can be
connected to VDD.
Power Supply Decoupling
The ADATE304 is a high performance device that requires
close attention to power supply decoupling to deliver the best
performance. The use of full power planes with low inductance
capacitors placed as close to the power pins as possible is recom-
mended. The following power connections are the most important:
• VPLUS to AGND (for the HVOUT driver)
• VDD to VSS near the DUTx pin (for the driver)
• VDD and VSS to AGND near the DUTx pin (for the
comparators)
• VCC to DGND (for the digital)
Additionally, large bulk capacitors (that is, 10 μF) should be
used on every power supply on the printed circuit board (PCB).

DETAILS OF DACS vs. LEVELS
There are ten 14-bit DACs per channel. These DACs provide
levels for the driver, comparator, load currents, VHH buffer, OVD,
and clamp levels. There are three versions of output levels as
follows:
• −2.5 V to +7.5 V and tracks DUTGND. Controls the VH,
VL, VT/VCOM/VHH, VOH, VOL, VCH, and VCL levels.
• −3.0 V to +7.0 V and tracks DUTGND. Controls the
OVD levels.
• −2.5 V to +7.5 V and does not track DUTGND. Controls
the IOH and IOL levels.
There is one 16-bit DAC per channel. This DAC provides the
levels for the PMU. The output level is as follows:
• −2.5 V to +7.5 V and tracks DUTGND; controls the
PMU levels.

RECOMMENDED PMU MODE SWITCHING
SEQUENCES
To minimize any possible aberrations and voltage spikes on the
DUT output, specific mode switching sequences are recommended
for the following transitions:
• PMU disable to PMU enable.
• PMU force voltage mode to PMU force current mode.
• PMU force current mode to PMU force voltage mode.
