SY88422LMG-TR

Overview

The SY88422LMG-TR is a single-supply laser driver designed for telecom and datacom applications operating up to 4.25Gbps. It delivers modulation current up to 90mA and bias current up to 100mA with a typical power supply current of 35mA. The device operates from a single 3.3V supply and is housed in a small form factor 16-pin QFN package measuring 3mm x 3mm.

Feature Summary

• Integrated bias and monitor functions for precise laser control
• Single 3.3V supply operation reduces system complexity
• Small form factor 16-pin QFN package optimizes board space

Applications

• Multi-rate LAN and MAN applications up to 4.25Gbps
• Fibre Channel (FC) systems
• GbE and SONET/SDH interfaces
• SFF and SFP modules
• LX-4 modules

Procurement Notes

Verify the specific suffix 'LMG-TR' corresponds to the 16-pin QFN package and tape-and-reel delivery format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 3.3V supply voltage matches your system design constraints before procurement.

Selection Notes

Select this component when a compact, single-supply laser driver is required for speeds up to 4.25Gbps. Consider the 90mA modulation current capability for driving standard laser diodes. Evaluate the 16-pin QFN footprint against available PCB real estate. Verify thermal management needs given the 35mA typical supply current.
