Procurement Notes

Verify the specific revision level and manufacturing date code upon order confirmation, as this part number indicates a discontinued status. Ensure that the receiving facility has appropriate moisture sensitivity handling procedures due to the QFN packaging type. Confirm compatibility with existing board layouts regarding the 16-pin thermal pad configuration before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring a single-channel driver for speeds up to 11.3 Gbps with integrated bias control. Consider the 16-QFN package size constraints and thermal dissipation requirements associated with the bare pad design. Evaluate the 3V to 3.6V supply voltage range against system power availability and ensure the 60mA modulation current meets the target laser diode specifications.

Part Context

This device belongs to the SY88022 family of laser drivers from Microchip Technology, originally developed under Micrel. It serves as a specialized integrated circuit for driving laser diodes in high-bandwidth optical communication links. The product line focuses on providing compact solutions for datacom and telecom applications where space efficiency and performance are critical design parameters.

Replacement Considerations

No direct public substitute part numbers are confirmed for this discontinued component. Designers should evaluate alternative laser drivers from the same manufacturer or other suppliers that match the 11.3 Gbps speed, 16-QFN package, and electrical specifications.
