The AD9125-M5372-EBZ is an AD9125 evaluation board along with the ADL5372 modulator on board. To operate the evaluation boards, the user must apply power, a clock source, a digital data source, and be able to observe the DAC output on either a spectrum analyser 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 and clock circuitry can be programmed into any of its various operating modes. The AD9125 is a dual, 16bit, high dynamic range TxDAC+ digital to analog converter (DAC) that provides a sample rate of 1000MSPS, permitting a multicarrier generation up to the nyquist frequency. It includes features optimised for direct conversion transmit applications, including complex digital modulation, and gain and offset compensation.
