GENERAL DESCRIPTION
This document describes the evaluation board for the AD9276
and AD9277, which provides all of the support circuitry required
to operate the AD9276 and AD9277 in their various modes and
configurations. The application software used to interface with
the devices is also described.
The AD9276 and AD9277 data sheets, available at
, provide additional information and should be
consulted when using the evaluation board. All documents and
software tools are available at
. For
