AD9212
EVALUATION BOARD
The AD9212 evaluation board provides all of the support cir-
cuitry required to operate the ADC in its various modes and
configurations. The converter can be driven differentially through a
transformer (default) or through the AD8334 driver. The ADC
can also be driven in a single-ended fashion. Separate power pins
are provided to isolate the DUT from the AD8334 drive circuitry.
Each input configuration can be selected by proper connection
of various jumpers (see Figure 76 to Figure 80). Figure 74 shows
the typical bench characterization setup used to evaluate the ac
performance of the AD9212. 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 76 to Figure 86 for the complete schematics and
layout diagrams that demonstrate the routing and grounding
techniques that should be applied at the system level.
POWER SUPPLIES
This evaluation board comes with a wall-mountable switching
power supply that provides a 6 V, 2 A maximum output. Simply
connect the supply to the rated 100 V ac to 240 V ac wall outlet
at 47 Hz to 63 Hz. The other end is a 2.1 mm inner diameter
jack that connects to the PCB at P701. Once on the PC board,
the 6 V supply is fused and conditioned before connecting to
three low dropout linear regulators that supply the proper bias
to each of the various sections on the board.
When operating the evaluation board in a nondefault condition,
L701 to L704 can be removed to disconnect the switching
power supply. This enables the user to bias each section of the
board individually. Use P702 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_DUT and DRVDD_DUT; however, it is
recommended that separate supplies be used for both analog
and digital. To operate the evaluation board using the VGA
option, a separate 5.0 V analog supply is needed. The 5.0 V
supply, or AVDD_5 V, should have a 1 A current capability. To
operate the evaluation board using the SPI and alternate clock
options, a separate 3.3 V analog supply is needed in addition to
the other supplies. The 3.3 V supply, or AVDD_3.3 V, should
have a 1 A current capability as well.
INPUT SIGNALS
When connecting the clock and analog source, use clean signal
generators with low phase noise, such as Rohde & Schwarz SMHU
or HP8644 signal generators or the equivalent. Use a 1 m, shielded,
RG-58, 50 Ω coaxial cable for making connections to the evalu-
ation board. Enter the desired frequency and amplitude from the
ADC specifications tables. Typically, most Analog Devices
evaluation boards can accept ~2.8 V p-p or 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. Analog Devices uses TTE, Allen
Avionics, and K&L types of band-pass filters. The filter should
be connected directly to the evaluation board if possible.
OUTPUT SIGNALS
The default setup uses the HSC-ADC-FPGA high speed
deserialization board to deserialize the digital output data and
convert it to parallel CMOS. These two channels interface
directly with the Analog Devices standard dual-channel FIFO
data capture board (HSC-ADC-EVALB-DC). Two of the eight
channels can then be evaluated at the same time. For more
information on channel settings on these boards and their
optional settings, visit www.analog.com/FIFO.
