ADN2806ACPZ-500RL7

Overview

The ADN2806ACPZ-500RL7 is a clock and data recovery (CDR) integrated circuit designed for SONET OC-12 applications. It provides receiver functions for clock and data recovery, as well as data retiming for 622 Mbps NRZ data streams. The device automatically locks to the input data rate without requiring an external reference clock or manual programming. It operates on a single 3.3 V supply with typical power consumption of 359 mW. The unit features LVDS outputs and CML inputs, housed in a compact 32-lead LFCSP package.

Feature Summary

• Exceeds SONET requirements for jitter transfer, generation, and tolerance
• Patented clock recovery architecture eliminates need for external reference clock
• Includes I²C interface for accessing optional features and configuration
• Provides loss-of-lock indicator and supports squelch modes

Applications

• SONET OC-12 systems
• BPON ONT implementations
• WDM transponders
• Regenerators and repeaters
• Broadband cross-connects and routers

Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm RoHS compliance status prior to integration. Ensure proper ESD handling procedures are followed during storage and assembly due to device sensitivity. Check current availability status as supply may be restricted.

Selection Notes

Select this component for designs requiring automatic lock to 622 Mbps data rates without external reference clocks. Ensure the PCB layout accommodates the 32-LFCSP-WQ (5x5) package dimensions. Verify that the application environment stays within the -40°C to +85°C operating temperature range.

Part Context

This part belongs to the ADN2806 series of clock and data recovery ICs manufactured by Analog Devices Inc. It is specifically optimized for high-performance optical communication interfaces meeting stringent SONET standards.

Replacement Considerations

Direct pin-to-pin replacements should be verified against the latest Analog Devices ordering guide. Alternative parts must match the 622 Mbps data rate capability and 32-lead LFCSP package form factor.
