Overview
The SY88822VKI is a high-speed current switch laser driver manufactured by Microchip Technology, designed for driving semiconductor laser diodes in optical transmission applications. It operates with a single supply voltage ranging from 3V to 5.5V and supports data rates up to 155Mbps. The device features a modulation current capability of 30mA and a supply current of 25mA. It is housed in a 10-pin MSOP package with an operating temperature range of -40°C to 85°C.
Feature Summary
- High-speed current switching for optical transmission
- Single supply voltage operation
- Integrated bias and modulation control
Applications
- Driving semiconductor laser diodes
- Optical transmission systems
- Fiber optic communication modules
Procurement Notes
Verify the specific suffix 'VKI' against official Microchip documentation to confirm pinout and electrical characteristics match the intended design requirements. Ensure compatibility with the target laser diode's forward voltage and current specifications. Check for moisture sensitivity level handling during assembly to prevent package damage.
Selection Notes
Select this component for applications requiring reliable laser drive at lower data rates such as SONET/SDH OC-3. Consider the 10-pin MSOP package size for space-constrained designs. Evaluate the 30mA modulation current limit against the specific laser diode requirements to ensure adequate drive strength without exceeding device limits.
Part Context
The SY88822 series includes variants like SY88822VKG and SY88822VKC, differing primarily in packaging or tape/reel configurations. The VKI variant is part of this family, sharing core functional specifications while potentially differing in mechanical or ordering attributes defined by the manufacturer.
Replacement Considerations
Direct substitutes within the same family include SY88822VKG and SY88822VKC. Verify if the alternative package type (Tube vs. Tape & Reel) meets production needs. Cross-reference with other Microchip laser drivers like the SY88422L only if higher data rates are required.
