Procurement Notes

Verify availability status carefully as this part is listed as obsolete or discontinued in official channels. Check for End-of-Life notifications from Renesas Electronics. Sourcing may be limited to surplus distributors only. Confirm package type and revision level against original design specifications before procurement.

Selection Notes

Select this component only if designing for legacy 14 Gbps Ethernet optical receivers requiring a four-channel TIA solution. Consider that it is an obsolete part; verify long-term supply chain stability. Ensure compatibility with existing ORTA family design rules. Evaluate alternative modern components if new designs are required.

Part Context

This device is part of Renesas Electronics' portfolio of high-speed analog ICs, formerly associated with IDT's optical communication products. It serves as a specialized building block for optical transceivers, providing the necessary amplification stage for converting photocurrent into voltage signals in high-bandwidth networking equipment.

Replacement Considerations

Official substitutes are not explicitly documented in the provided source material. Consult Renesas Electronics directly for current obsolescence management plans or recommended replacement families within the ORTA series.
