AD800-52BRZ

Overview

The AD800-52BRZ is a clock and data recovery integrated circuit designed for telecommunications applications. It employs a second-order phase-locked loop architecture to recover clocks from Non-Return to Zero (NRZ) data without requiring a preamble or external voltage-controlled crystal oscillator (VCXO). The device supports the STS-1 standard at a nominal center frequency of 51.84 Mbps. It accepts differential ECL input data and provides differential ECL outputs for both the recovered clock and retimed data. The unit operates on a single supply voltage ranging from -4.5 V to -5.5 V and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports STS-1 data rates with a nominal center frequency of 51.84 Mbps
• Acquires lock on random or scrambled NRZ data without preamble requirements
• Provides differential ECL compatible inputs and outputs
• Includes a precisely trimmed internal VCO eliminating external frequency setting components

Applications

• Telecommunications systems utilizing DS-3 or STS-1 standards
• Clock recovery circuits for high-speed digital data streams
• Data retiming applications in network infrastructure equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm the specific suffix 'BRZ' corresponds to the plastic SOIC package variant with lead-free composition. Request current production status documentation as availability may vary based on manufacturing lifecycle stages.

Selection Notes

Select this model specifically for STS-1 (51.84 Mbps) applications; use AD800-45BRZ for DS-3 (44.736 Mbps) requirements. Ensure the design accommodates the required loop damping capacitor value, which determines jitter peaking and acquisition time. Verify that the system power supply can provide the necessary current while maintaining stability within the specified voltage range.

Part Context

This component belongs to the AD800/AD802 family of PLL-based clock recovery devices. The AD800 series covers lower data rates including DS-3 and STS-1, while the AD802 series addresses higher speeds like STM-1. The BRZ suffix indicates a RoHS-compliant plastic Small Outline Integrated Circuit (SOIC) package suitable for surface mount technology.
