Overview
The AD9861BCPZ-50 is a mixed-signal front-end (MxFE) baseband transceiver designed for broadband applications by Analog Devices Inc. This integrated circuit combines dual 10-bit analog-to-digital converters (ADCs) and dual 10-bit digital-to-analog converters (TxDACs), making it a versatile solution for various communication systems. The device is packaged in a 64-lead LFCSP (low profile, fine pitched, chip scale package) with a compact footprint of 9 mm x 9 mm, suitable for tightly spaced applications such as PCMCIA cards.
