SY88022LMG

Overview

The SY88022LMG is a single-channel laser diode driver designed for fiber optic applications. It supports data rates up to 11.3Gbps and operates from a 3V to 3.6V supply. Key electrical parameters include a typical supply current of 65mA, modulation current capability of 60mA, and bias current of 80mA. The device is housed in a compact 16-VFQFN package with exposed pad (3mm x 3mm). It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports high-speed optical transmission at data rates up to 11.3Gbps
• Integrates bias and modulation control for direct laser diode driving
• Utilizes a small form factor QFN package for space-constrained designs

Applications

• High-speed fiber optic transceivers
• Optical interconnect modules
• Datacom communication systems

Procurement Notes

Verify component status as the SY88022LMG is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compatibility with existing design specifications before procurement due to potential discontinuation risks.

Selection Notes

Select this component for applications requiring a single-channel driver with high bandwidth up to 11.3Gbps. Consider the 16-pin QFN footprint for PCB layout constraints. Verify that the 3V-3.6V supply voltage aligns with system power rails. Evaluate thermal performance given the 65mA supply current in the specified operating temperature range.

Part Context

This part belongs to the Microchip SY88022 series of laser drivers. It is distinct from lower-speed variants like the SY88422L (4.25Gbps) or amplifiers like the SY88083. The 'LMG' suffix typically denotes the specific package type and temperature grade within the product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative components must be selected based on functional equivalence (data rate, package, and electrical specs) rather than direct cross-reference lists.
