The document introduces the Analog Devices Mixed-Signal Front-End (MxFE™) Baseband Transceiver for Broadband Applications AD9861 Rev. 0. The product includes dual 10-bit analog-to-digital converters and dual 10-bit digital-to-analog converters with internal or external reference, with versions available at 50 MSPS and 80 MSPS. The product also features programmable gain control and a configurable internal clock distribution block. Various data transfer modes can be achieved through register programmability or limited programmability through mode pins. Independent power-down control pins are provided for Rx and Tx.
The AD9861 is a mixed‑signal front‑end (MxFE) baseband transceiver designed for broadband communication applications. It integrates dual 10‑bit ADCs and dual 10‑bit DACs with selectable interpolation rates and programmable gain control, and is supplied by a single 3.3 V rail.
The handbook provides detailed specifications for the Tx and Rx paths, power and digital characteristics, timing diagrams, absolute maximum ratings, pin configurations, and typical performance data. It also includes ordering information and a revision history for the device.
