GENERAL DESCRIPTION

The AD9866 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.
