EVALUATION BOARD OVERVIEW
EVALUATION BOARD OPERATION
The AD9776A/AD9778A/AD9779A evaluation board is provided
to help users quickly become familiar with the operation of the
device and to evaluate the device performance. To operate the
evaluation board, the user needs a PC, a 5 V power supply, a
clock source, and a digital data source. The user also needs a
spectrum analyzer or an oscilloscope to observe the DAC output.

The typical evaluation setup is shown in Figure 100. A sine or
square wave clock can be used to source the DAC sample clock.
The spectral purity of the clock directly affects the device per-
formance. A low noise, low jitter clock source is required.
All necessary connections to the evaluation board are shown in
more detail in Figure 101.
