AD9139-DUAL-EBZ

The AD9139-DUAL-EBZ evaluation board connects to a Data Pattern Generator 3 (DPG3) for quick evaluation of AD9139 high speed, signal processing digital to analog converter. The AD9139 is a 16bit, high dynamic range digital to analog converter (DAC) that provides a maximum update rate of 1600MSPS, permitting multicarrier generation up to the nyquist frequency. The DPG3 automatically formats the data and sends it to the AD9139-DUAL-EBZ, simplifying evaluation of the AD9139 device. The evaluation board (EVB) runs from a +5V supply. A clock distribution chip AD9516 is included on this EVB as a clock fan out and frequency divider for the DACCLK, REFCLK, Frame and DPG3 input clock. Also included is a quadrature modulator ADL5375 for quick DAC+IQMOD evaluation. Since AD9139 is a single channel converter, dual AD9139s are used on the board to work as I and Q, which typically applies to the case of wideband applications.
