The document introduces the AD9863 Rev. A model of the mixed-signal front-end (MxFE™) baseband transceiver, which is suitable for broadband applications. The product features dual 12-bit, 50 MSPS analog-to-digital converters and dual 12-bit, 200 MSPS digital-to-analog converters with internal or external reference. It also includes programmable gain control and clock distribution block. Various data transfer modes can be configured through register programmability or optionally limited programmability through mode pins. The product also has independent Rx and Tx power-down control pins, and a 64-lead LFCSP package.
The AD9863 is a mixed‑signal front‑end (MxFE) device that integrates dual 12‑bit ADCs and dual 12‑bit DACs for broadband communications. It offers a 24‑pin flexible I/O bus, programmable PLL, and supports both half‑duplex and full‑duplex data transfers. The device is supplied in a 64‑lead LFCSP package measuring 9 mm × 9 mm.
The datasheet provides complete electrical, timing, and power specifications, pin descriptions, absolute maximum ratings, and ordering information. It also includes functional block diagrams and typical performance characteristics for both the transmit (Tx) and receive (Rx) paths.
