• High-speed serial communication systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as distribution channels may list limited stock or end-of-life statuses. Ensure the TQFN-EP-24 footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component for designs requiring a single-channel laser driver with built-in diagnostics. Verify that the 3.2 Gbps speed meets the system bandwidth requirements. Ensure the 2.97 V to 3.63 V supply range aligns with the available power rails. Consider the thermal dissipation characteristics of the 24-TQFN package for the intended enclosure environment.
