The AD9763 is a dual port, high-speed, two-channel, 10-bit CMOS DAC. It integrates two high quality 10-bit TxDAC+ cores, a voltage reference and digital interface circuitry into a small 48-lead LQFP package. The AD9763 offers exceptional ac and dc performance while supporting update rates up to 125 MSPS. The AD9763 has been optimized for processing I and Q data in communications applications. The digital interface consists of two double-buffered latches as well as control logic. Separate write inputs allow data to be written to the two DAC ports independent of one another. Separate clocks control the update rate of the DACs.
