Overview
The AD800-52BRZ is a Clock and Data Recovery (CDR) integrated circuit manufactured by Analog Devices Inc. This device is designed to perform clock recovery and data retiming on Non-Return to Zero (NRZ) data streams. It employs a second-order phase-locked loop architecture, which is particularly effective for supporting data rates up to 52 Mbps, specifically targeting DS-3 and STS-1 telecommunications standards.
