Procurement Notes
Verify the specific suffix requirements for the GN1444-INE3 part number against current manufacturer documentation. Confirm RoHS compliance status and lead time availability directly with authorized distributors or Semtech sales representatives prior to ordering. Ensure the selected package matches the intended PCB layout constraints.
Selection Notes
Select this component when a combined TIA and laser driver solution is required in a small footprint. It is suitable for applications needing integrated limiting amplification alongside EML driving capabilities. Consider the 4x4mm package dimensions for space-constrained optical transceiver modules operating at speeds up to 11.3Gbps.
Part Context
This device belongs to Semtech’s FiberEdge® and DirectEdge™ product families, which provide analog linear drivers and TIAs for next-generation optical networks.
