Overview
The AD800-52BRZRL is a clock and data recovery integrated circuit (IC) designed by Analog Devices Inc. This device employs a second-order phase-locked loop (PLL) architecture to perform clock recovery and data re-timing on Non-Return to Zero (NRZ) data. It is specifically tailored to support standard telecommunications bit rates, particularly the 52 Mbps STS-1 rate. The AD800-52BRZRL does not require a preamble or an external Voltage-Controlled Crystal Oscillator (VCXO) to lock onto input data, making it a robust solution for various telecommunications applications.
