Overview
The SY88822VKC is a single-channel laser driver manufactured by Microchip Technology, designed for optical transmission applications. It operates with a data rate of 155Mbps and supports supply voltages of 3V to 3.6V or 4.5V to 5.5V. The device is housed in a 10-pin MSOP package and draws a typical supply current of 25mA. It delivers a modulation current up to 30mA, making it suitable for driving semiconductor laser diodes in fiber optic networks.
Feature Summary
- High-speed current switching capability for optical transmission
- Single-channel architecture optimized for laser diode drive
- Dual voltage range support for flexible system integration
Applications
- Driving semiconductor laser diodes in optical transmission systems
- Fiber optic network interface circuits
- Low-speed optical transceiver modules
Procurement Notes
Verify the specific suffix 'VKC' against official Microchip documentation to confirm the tube packaging variant versus tape-and-reel options. Ensure compatibility with the required operating temperature range and supply voltage specifications before procurement. Cross-reference the datasheet revision history for any recent changes to pinout or electrical characteristics.
Selection Notes
Select this component for designs requiring a dedicated laser driver at 155Mbps speeds. Consider the 10-MSOP package size for space-constrained PCB layouts. Evaluate the 25mA supply current consumption against system power budgets. Confirm that the 30mA modulation current meets the requirements of the target laser diode.
Part Context
The SY88822 series belongs to Microchip's portfolio of laser drivers intended for telecom and datacom applications. This family provides solutions for driving laser diodes in various optical networking standards. The SY88822VKC specifically targets lower-speed optical links compared to higher-gigabit variants in the same product line.
Replacement Considerations
Check for SY88822VKG or SY88822VKI as potential functional equivalents within the same series. Verify package compatibility and electrical parameter alignment before substitution.
