This file is AD9861 datasheet. AD9861 is a mixed-signal front-end (MxFE™) baseband transceiver launched by Analog Devices, mainly used for broadband applications.
The AD9861 is a mixed‑signal front‑end (MxFE) transceiver designed for broadband access, LAN and modem communications. It integrates dual 10‑bit analog‑to‑digital converters and dual 10‑bit digital‑to‑analog converters, offering 50 MSPS or 80 MSPS ADC operation and up to 200 MHz DAC update rates with selectable interpolation.
The device is supplied in a 64‑lead LFCSP package (9 mm × 9 mm) and features a flexible 20‑bit I/O bus, programmable PLL clock distribution, and independent power‑down control pins. Detailed electrical, timing, and absolute‑maximum‑rating specifications are provided for system designers.
