Overview
The AD9866BCPZ is a mixed-signal front end (MxFE®) integrated circuit (IC) designed by Analog Devices Inc. for transceiver applications. It supports both transmit (Tx) and receive (Rx) path functionalities with data rates up to 80 mega-samples per second (MSPS). The IC is particularly suited for half- and full-duplex applications due to its flexible digital interface, power-saving modes, and high Tx-to-Rx isolation. The AD9866BCPZ can often replace discrete ADC and DAC solutions, making it a versatile component for various communication systems.
