SY88822VKG

Overview

The SY88822VKG is a laser driver manufactured by Microchip Technology, designed for optical transmission applications. It operates as a high-speed current switch to drive semiconductor laser diodes. The device supports data rates up to 1.25 Gbps and functions with supply voltages ranging from 3.3V to 5V. It features a single channel configuration housed in a 10-pin MSOP package. The component draws a typical supply current of 25 mA and provides a modulation current capability of 25 mA.

Feature Summary

• Functions as a high-speed current switch specifically engineered for driving semiconductor laser diodes in optical transmission systems.

Applications

• Driving semiconductor laser diodes in optical transmission applications

Procurement Notes

Verify the specific suffix 'KG' corresponds to the tube packaging variant rather than the tape-and-reel option. Confirm the operating voltage range aligns with the system design requirements for 3.3V or 5V supplies. Ensure the MSOP-10 footprint matches the PCB layout specifications. Check for moisture sensitivity level compliance during storage and handling procedures.

Selection Notes

Select this component when a single-channel laser driver is required for optical links operating at speeds up to 1.25 Gbps. Consider the 10-pin MSOP package size for space-constrained designs. Evaluate the 25 mA modulation current limit against the specific laser diode requirements. Compare power consumption characteristics if low standby current is a priority.

Part Context

This part belongs to the SY88822 series of laser drivers from Microchip Technology. It is distinct from higher-speed variants like the SY88722 (622 Mbps) or lower-speed options within the same family. The device serves as a dedicated interface between digital logic and analog laser diodes in fiber optic communication modules.
