Specialized Procurement Notes

Verify the specific suffix against official Broadcom documentation, as the provided reference material primarily lists the SS28-0A00-02 variant. Confirm availability status directly with authorized distributors, as lead times may vary significantly due to manufacturing schedules. Ensure compliance with RoHS directives and check for any export control classifications relevant to the destination region before finalizing procurement orders.

Specialized Selection Notes

Select this component when designing systems requiring managed PCIe switching with low latency and high port density. Evaluate thermal requirements carefully, as high-speed switching generates significant heat. Compare power consumption metrics against alternative Gen 5 solutions to ensure alignment with system energy efficiency targets. Verify that the non-standard package footprint matches the PCB layout constraints of the target design.

Specialized Part Context

This part belongs to the Broadcom PEX89000 series, which represents the ninth generation of PCIe Gen 5.0 switches. These devices are engineered to replace legacy components that require protocol conversion, thereby reducing inherent latency and power usage. The series is widely adopted in cloud computing environments where scalability and performance per watt are critical design parameters.

Specialized Replacement Considerations

Direct substitutes within the same family include the SS28-0B00-00 (PEX89144), SS24-0B00-00 (PEX89104), and SS23-0B00-00 (PEX89088). Selection among these depends on the required number of lanes and ports. Ensure pin compatibility and software SDK support are verified before swapping between different lane counts in the PEX89000 lineup.
