• High-speed serial data transmission interfaces requiring laser control

Procurement Notes

Verify component status as the ADN2873ACPZ-RL is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing board designs before procurement, as replacement components may require design adjustments. Check for moisture sensitivity levels and storage conditions if sourcing from non-original packaging.

Selection Notes

Select this component when designing optical links requiring integrated laser drive and SFF-8472 compliance. Consider the 4.25 Gbps speed limit and 3V to 3.6V supply requirements. Evaluate thermal performance within the specified -40°C to +85°C range. Compare against newer generations if long-term supply stability is critical, as this specific part number faces discontinuation risks.

Part Context

The ADN2873 belongs to Analog Devices' family of laser diode drivers tailored for short-reach optical communications. It shares functional similarities with the ADN2870 but offers enhanced support for higher data rates and digital diagnostics via the SFF-8472 standard. This integration simplifies module design by combining drive functionality with monitoring capabilities in a compact surface-mount package.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the ADN2873ACPZ-RL is marked obsolete, engineers should consult Analog Devices for recommended next-generation replacements or equivalent third-party solutions that meet SFF-8472 and 4.25 Gbps requirements.
