Overview
The AD9861BCP-50, produced by Analog Devices Inc., is a member of the MxFE (Mixed-Signal Front End) family, designed for the communications market. 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 component for various broadband applications. The device is available in two speed grades: -50 and -80, with the -50 version optimized for ADC sampling rates of 50 MSPS and less, and the -80 version for higher sampling rates.
