AD9785/AD9787/AD9788 EVALUATION BOARD

The AD9785/AD9787/AD9788 devices share a common PCB with the only difference between the evaluation boards being the DUT that is populated. To operate the board, the user must apply power, a clock source, a digital data source, and be able to observe the DAC output on either a spectrum analyzer or an oscilloscope. A low jitter sine or square wave clock will work well as a source. The evaluation board comes with software which allows the user to program the SPI port. Via the SPI port, the DUT can be programmed into any of its various operating modes.
