AD9600
EVALUATION BOARD
The AD9600 evaluation board provides all of the support
circuitry required to operate the ADC in its various modes and
configurations. The converter can be driven differentially using the
double-balun configuration (default) or an AD8352 differential
driver. The ADC can also be driven in a single-ended fashion.
Separate power pins are provided to isolate the DUT from the
AD8352
by properly connecting various components (see Figure 74 to
Figure 83). Figure 73 shows the typical bench characterization
setup used to evaluate the ac performance of the AD9600.
It is critical that the signal sources used for the analog input and
clock have very low phase noise (<<1 ps rms jitter) to realize the
optimum performance of the converter. Proper filtering of the
analog input signal to remove harmonics and lower the integrated
or broadband noise at the input is also necessary to achieve the
specified noise performance.
See Figure 74 to Figure 91 for the complete schematics and
layout diagrams that demonstrate the routing and grounding
techniques that should be applied at the system level.
POWER SUPPLIES
The evaluation board comes with a wall-mountable switching
power supply that provides a 6 V, 2 A maximum output. Connect
the supply to the rated 100 V ac to 240 V ac wall outlet at 47 Hz
to 63 Hz. The output of the supply is a 2.1 mm inner diameter
circular jack that connects to the PCB at J16. Once on the PC
board, the 6 V supply is fused and conditioned before connecting
to six low dropout linear regulators that supply the proper bias
to each of the various sections of the board.

The evaluation board can be operated using external supplies
by removing L1, L3, L4, and L13 to disconnect the voltage
regulators supplied from the switching power supply. This
enables the user to individually bias each section of the board.
Use P3 and P4 to connect a different supply for each section.
At least one 1.8 V supply is needed with a 1 A current capability
for AVDD and DVDD; a separate 1.8 V to 3.3 V supply is
recommended for DRVDD. To operate the evaluation board
using the AD8352 driver, a separate 5.0 V supply (AMP VDD)
with a 1 A current capability is needed. To operate the evaluation
board using the alternative SPI options, a separate 3.3 V analog
supply (VS) is needed in addition to the other supplies. The
3.3 V supply (VS) should also have a 1 A current capability.
Using Solder Jumper SJ35 allows the user to separate AVDD
and DVDD if desired.
INPUT SIGNALS
When connecting the clock and analog sources to the evaluation
board, use clean signal generators with low phase noise, such as
Rohde & Schwarz SMA100A or Agilent HP8644 signal generators
or the equivalent, as well as a 1 m, shielded, RG-58, 50 Ω coaxial
cable. Enter the desired frequency and amplitude for the ADC.
The AD9600 evaluation board from Analog Devices can accept
a ~2.8 V p-p or a 13 dBm sine wave input for the clock. When
connecting the analog input source, it is recommended to use a
multipole, narrow-band, band-pass filter with 50 Ω terminations.
Good choices of such band-pass filters are available from TTE,
Allen Avionics, and K&L Microwave, Inc. Connect the filter
directly to the evaluation board, if possible.
OUTPUT SIGNALS
The parallel CMOS outputs interface directly with the Analog
Devices standard ADC data capture board (HSC-ADC-
EVALCZ). For more information on the ADC data capture
boards and their optional settings, visit www.analog.com/FIFO.
