SY88232LMG

Overview

The SY88232LMG is a single-supply 3.3V integrated laser driver and post-amplifier designed for telecom and datacom applications. It supports data rates from 155Mbps up to 2.5Gbps. The device delivers modulation current up to 85mA and provides high compliance voltage suitable for high-current operation with DC-coupled lasers. It features an integrated Automatic Power Control (APC) circuit, bias and power monitoring capabilities, and a high-sensitivity post-amplifier capable of detecting signals as low as 5mVPP. The component is housed in a 32-pin QFN package.

Procurement Notes

Verify the specific suffix and package configuration against official Microchip documentation to ensure compatibility with target designs. Confirm that the 32-pin QFN form factor aligns with PCB layout requirements. Check for any recent lifecycle updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a combined laser driver and post-amplifier solution is required for 2.5Gbps applications. Ensure the design accommodates the 3.3V single-supply requirement and utilizes the integrated APC features for laser stability. Consider the 32-pin QFN footprint during schematic capture and verify thermal dissipation needs for the specific enclosure.
