Procurement Notes

Verify the specific suffix 'RGPR' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier documentation. Check for obsolescence notices or lifecycle changes, as availability may vary by region. Ensure the ordering part number matches the exact electrical and mechanical requirements of the design.

Selection Notes

Select this component when a differential drive solution for VCSELs is required at speeds up to 11.3 Gbps. Consider the 20-QFN footprint for board space constraints. Evaluate the 90 mA supply current against system power budgets. Verify compatibility with the intended VCSEL forward voltage and impedance requirements before finalizing the design.
