The AD9776/AD9778/AD9779 evaluation board has been designed to optimize performance of the DAC, as well as for ease of customer use and digital interface. 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 sine or square wave clockwill work well as a source. The AD9779 evaluation board comes with software which allows the user to program the SPI port. Via the SPI port, the AD9779 can be programmed into any of its various operating modes.
An AD8349 Quadrature Modulator is included on the evaluation board to facilitate evaluation of direct conversion or single sideband transmit architectures.
