PEX8680-AA50RBC F

Analog Switches - Special Purpose Overview

The PEX8680-AA50RBC F is a PCIe Gen2 switch manufactured by Broadcom Limited. It supports a data rate of 5.0 GT/s and provides 80 lanes across 20 ports. The component operates within a temperature range of -5°C to +85°C and utilizes an I2C interface for management. It is housed in an FCBGA-1156 package designed for surface mount technology. This device belongs to the PCI Interface IC category, specifically functioning as a high-port-count switch for system connectivity.

Analog Switches - Special Purpose Feature Summary

• Provides extensive connectivity through a 20-port architecture supporting up to 80 lanes
• Enables high-speed data transfer using PCIe Generation 2 specifications at 5.0 GT/s
• Supports industrial-grade operational environments with extended temperature tolerance

Analog Switches - Special Purpose Applications

• High-density server backplane expansion
• Storage area network (SAN) fabric interconnects
• Enterprise networking infrastructure switches

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix designation carefully, as the requested model ends in 'F' while official documentation primarily references the 'G' variant. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may be restricted or subject to end-of-life notices. Ensure the procurement channel provides valid traceability for this discontinued or limited-supply component.

Analog Switches - Special Purpose Selection Notes

Select this component when a design requires a large number of PCIe endpoints without external switching complexity. Compare lane counts against alternative models like the PEX8696 if higher density is needed. Verify that the FCBGA-1156 footprint matches the PCB layout constraints. Ensure the thermal design accommodates the specified operating temperature range for the target application environment.

Analog Switches - Special Purpose Part Context

This part belongs to the Broadcom PEX86xx series of PCIe switches, which are widely used in enterprise and data center applications. The PEX8680 represents a mid-to-high tier solution within this family, offering more ports than smaller variants like the PEX8624 but fewer than the top-tier PEX8696. It serves as a critical interconnect element in complex computing systems requiring scalable PCIe topology.

Analog Switches - Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Broadcom's official obsolescence notifications or contact technical support for validated replacement recommendations. Alternative solutions may require redesigning the PCB footprint due to differences in pinout or package dimensions.
