GENERAL DESCRIPTION

The AD9865 is a mixed-signal front end (MxFE) IC for transceiver applications requiring Tx and Rx path functionality with data rates up to 80 MSPS. 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 AD9865 to replace discrete ADC and DAC solutions. Power saving modes include the ability to reduce power consumption of individual functional blocks, or to power down unused blocks in half-duplex applications.
