• Supports multiple nontransparent bridging functions (NTB)
• Includes on-board DMA support and internal buffering

Applications

• High-performance server system interconnect switching
• Storage area network infrastructure
• Enterprise computing platforms requiring multi-root topology

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper handling procedures are followed given the fine-pitch BGA package requirements.

Selection Notes

Select this model when 32 lanes and 8 downstream ports are required for PCIe Gen2 systems. Consider thermal management capabilities for the FCBGA package in dense layouts. Verify voltage domain compatibility with connected peripherals before integration.

Part Context

This component belongs to the IDT/Renesas 89H32 series of PCIe switches. It serves as a critical interconnect solution for expanding PCIe connectivity in complex electronic systems. The part represents a transition from legacy IDT products under the Renesas Electronics portfolio.

Replacement Considerations

Check for direct pin-compatible substitutes within the same family. Evaluate newer generation PCIe switches if bandwidth upgrades are necessary. Verify firmware compatibility if migrating between different switch controller versions.
