EVALUATION BOARD
Evaluation boards are offered to configure the AD9444 in
either CMOS or LVDS mode. Each represents a recommended
configuration for using the device over a wide range of sample
rates and analog input frequencies. These evaluation boards
provide all the support circuitry required to operate the ADC in
its various modes and configurations. Complete schematics and
layout plots follow and demonstrate 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
(< 1 ps rms jitter) be 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 an ac to 6 V dc power
supply. The evaluation boards include low dropout regulators to
generate the various dc supplies required by the AD9444 and its
support circuitry. Separate power supplies are provided to iso-
late the DUT from the support circuitry. Each input configura-
tion can be selected by proper connection of various jumpers
Both the LVDS and CMOS versions of the evaluation board are
