• Enables flexible host and downstream port assignment via ExpressFabric architecture
• Includes an on-chip PCIe analyzer with GUI support for diagnostics

Specialized Applications

• Machine learning and artificial intelligence systems
• Composable hyper-scale compute systems
• High-performance server and storage applications

Specialized Procurement Notes

Verify authenticity carefully as market prices are high and counterfeit risks exist. Confirm supply status directly with authorized channels due to limited availability. Ensure the ordering suffix matches the required configuration without assuming functional changes based solely on suffix variations.

Specialized Selection Notes

Select this component for designs requiring maximum PCIe bandwidth and low latency. Evaluate thermal requirements for the BGA package. Ensure compatibility with standard PCIe endpoints and software stacks. Consider system complexity reduction benefits when designing scalable fabrics.

Specialized Part Context

This part belongs to the PEX89000 series, which represents Broadcom's latest generation of PCIe switches designed for advanced computing. It succeeds earlier generations like the PEX8700 and PEX8900 series, offering significantly higher throughput for modern data center workloads.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified documentation. Direct replacements within the same series may require validation of lane counts and pin compatibility.
