Procurement Notes

Verify the specific suffix 'T' against official Analog Devices documentation to confirm reel packaging specifications. Confirm current availability status as distribution channels may list this part as limited or discontinued. Ensure compatibility with existing PCB footprints for the 20-TQFN package before procurement.

Selection Notes

Select this component when designing SONET/SDH infrastructure requiring CDR functionality at rates up to 2.67Gbps. Verify that the system power supply remains within the 3V to 3.6V range. Ensure the design accommodates CML signaling requirements for both input and output stages. Check thermal management needs for the 20-TQFN package within the specified -40°C to +85°C operating window.

Part Context

This part belongs to the MAX3873 family of clock and data recovery ICs. It serves as a specialized timing solution for high-speed serial communication standards. The device integrates limiting amplifier functions to condition recovered signals. It is distinct from general-purpose clock generators by its focus on data recovery and retiming capabilities.
