SY88236LMG

Overview

The SY88236LMG is a laser diode driver from Microchip Technology, designed for burst-mode operation with an integrated post amplifier. It supports data rates up to 2.5Gbps and operates on a single supply voltage ranging from 3V to 3.6V. The device features a modulation current of 85mA and a bias current of 70mA, with a typical operating supply current of 90mA. It is housed in a 32-lead VFQFN exposed pad package (32-QFN, 5x5mm), suitable for small-form-factor applications.

Feature Summary

• Supports burst-mode laser diode driving with integrated post-amplifier functionality
• Optimized for high-speed data transmission at 2.5Gbps data rates
• Operates within a standard 3V to 3.6V single power supply range

Applications

• Datacom optical transceivers
• Ethernet Gigabit interfaces
• Fiber optic communication modules

Procurement Notes

Verify the specific suffix (e.g., -TR for tape and reel) against your assembly requirements, as availability may vary by packaging configuration. Confirm RoHS compliance status and lead-free certification through official Microchip channels or authorized distributors before ordering. Check for obsolescence notices or lifecycle changes directly from the manufacturer to ensure long-term supply stability.

Selection Notes

Select this component when burst-mode operation is required for laser diodes in compact optical modules. Ensure the design accommodates the 32-QFN thermal pad for adequate heat dissipation. Verify that the system power supply remains stable within the 3V to 3.6V window to maintain signal integrity and prevent driver malfunction during high-speed data transitions.

Part Context

This part belongs to the SY882xx series of laser drivers from Microchip Technology, formerly Micrel. It is engineered specifically for VCSEL and edge-emitting laser diodes in short-reach optical interconnects. The integration of the post amplifier reduces external component count, simplifying PCB layout and improving overall system reliability in dense networking equipment.
