AD9460
EVALUATION BOARD
Evaluation boards are offered to configure the AD9460 in either
CMOS mode or LVDS mode only. This design represents a
recommended configuration for using the device over a wide
range of sampling rates and analog input frequencies. These
evaluation boards provide all the support circuitry required to
operate the ADC in its various modes and configurations. Com-
plete schematics are shown in Figure 50 through Figure 53. Gerber
files are available from engineering applications demonstrating
the proper routing and grounding techniques that should be
applied at the system level.
It is critical that signal sources with very low phase noise
(<60 fsec rms jitter) are used to realize the ultimate
performance of the converter. Proper filtering of the input
signal to remove harmonics and lower the integrated noise at
the input is also necessary to achieve the specified noise
performance.
The evaluation boards are shipped with a 115 V ac to 6 V dc
power supply. The evaluation boards include low dropout
regulators to generate the various dc supplies required by the
AD9460 and its support circuitry. Separate power supplies are
provided to isolate the DUT from the support circuitry. Each
input configuration can be selected by proper connection of
various jumpers (see Figure 50).

The LVDS mode evaluation boards include an LVDS-to-
CMOS translator, making them compatible with the high
speed ADC FIFO evaluation kit (HSC-ADC-EVALA-SC,
www.analog.com/FIFO). The kit includes a high speed data
capture board that provides a hardware solution for capturing
up to 32 kB samples of high speed ADC output data in a FIFO
memory chip (user upgradeable to 256 kB samples). Software
is provided to enable the user to download the captured data to
a PC via the USB port. This software also includes a behavioral
model of the AD9460 and many other high speed ADCs.
Behavioral modeling of the AD9460 using ADIsimADC™
software is also available at www.analog.com/ADIsimADC. The
ADIsimADC software supports virtual ADC evaluation using ADI
proprietary behavioral modeling technology. This allows rapid
comparison between the AD9460 and other high speed ADCs
with or without hardware evaluation boards.
The user can choose to remove the translator and terminations
to access the LVDS outputs directly.
