The AD9866BCPZ is a Mixed-signal Front End (MxFE) IC for transceiver applications requiring Tx and Rx path functionality with data rates up to 80MSPS. Its flexible digital interface, power saving modes and high Tx-to-Rx isolation make it well-suited for half- and full-duplex applications. The digital interface is extremely flexible allowing simple interfaces to digital back ends that support half- or full-duplex data transfers, thus often allowing the AD9866 to replace discrete ADC and DAC solutions. An on-chip PLL clock multiplier and synthesizer provide all the required internal clocks, as well as two external clocks from a single crystal or clock source. The transmit path signal bandwidth can be as high as 34MHz at an input data rate of 80MSPS. The TxDAC provides differential current outputs that can be steered directly to an external load or to an internal low distortion current amplifier.
