EVALUATION BOARD
GENERAL DESCRIPTION
The AD9763-EB is an evaluation board for the AD9763 10-bit
dual digital-to-analog converter. Careful attention to layout and
circuit design, combined with a prototyping area, allow the user
to easily and effectively evaluate the AD9763 in any application
where high resolution, high speed conversion is required.
This board allows the user the flexibility to operate the AD9763
in various configurations. Possible output configurations

include transformer coupled, resistor terminated, and single and
differential outputs. The digital inputs can be used in dual port
or interleaved mode, and are designed to be driven from various
word generators, with the on-board option to add a resistor
network for proper load termination. When operating the
AD9763, best performance is obtained when running the digital
supply (DVDD) at 3.3 V and the analog supply (AVDD) at 5 V.
