Procurement Notes

This component is classified as obsolete or end-of-life. Verification of current availability requires direct consultation with authorized distributors or the manufacturer. Supply chain status may involve limited stock or alternative sourcing strategies due to discontinuation.

Selection Notes

Engineers should evaluate partitionable architecture requirements and multi-root support needs when selecting this switch. Compatibility with PCIe Gen2 specifications and voltage levels must be confirmed against system design constraints before integration into legacy or existing hardware platforms.

Part Context

This part belongs to the 89H22H16G2 series of PCIe switches. It shares architectural similarities with other models in the family, such as the 89H64H16G2, but differs in lane count and port configuration. The series targets deterministic system interconnect applications requiring non-blocking throughput.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official Renesas resources for recommended upgrades or equivalent components.
