Procurement Notes
Verify the specific suffix 'LRGET' against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and packaging details. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for product discontinuation notices or lifecycle changes from Texas Instruments before finalizing procurement plans.
Selection Notes
Select this component when a single-channel driver is required for 11.3Gbps optical links. Ensure the system power supply accommodates the 2.97V to 3.63V input range. Verify that the 24-VQFN package footprint matches the PCB design constraints. Consider thermal management capabilities given the 100°C maximum operating temperature rating.
Part Context
This part belongs to the ONET1101 family of laser drivers from Texas Instruments. It shares core specifications with variants like ONET1101L and ONET1101LRGER, differing primarily in packaging and tape/reel configurations. The LRGET suffix indicates a specific reel size and tape type for automated assembly processes.
Replacement Considerations
ONET1101LRGER is a documented alternative within the same family, offering identical electrical performance but potentially different packaging quantities. Verify pin compatibility and thermal dissipation requirements when substituting.
