The AD9863 Rev. A is a mixed-signal front-end (MxFE™) baseband transceiver from Analog Devices that is suitable for broadband applications. The AD9863 Rev. A has dual 12-bit, 50 MSPS analog-to-digital converters and dual 12-bit, 200 MSPS digital-to-analog converters, and supports internal or external references. The AD9863 Rev. A also supports various interleaved or noninterleaved data transfer modes, and can operate in half-duplex mode or full-duplex mode. The AD9863 Rev. A uses a 24-pin flexible I/O data interface, and supports programming through registers or through mode pins. The AD9863 Rev. A also has independent Rx and Tx power-down control pins, and a 64-lead LFCSP package (9 mm × 9 mm).
The AD9863 is a mixed‑signal front‑end (MxFE) transceiver that integrates dual 12‑bit ADCs and dual 12‑bit DACs for broadband communications. It supports 50 MSPS ADC sampling and up to 200 MHz DAC update rates, with configurable interpolation and programmable gain.
The document includes detailed specifications for the Tx and Rx paths, power requirements, timing, absolute maximum ratings, pin functions, package dimensions, and ordering information, enabling designers to integrate the device into compact, high‑performance systems.
