PEX8616-BB50RBC F

Analog Switches - Special Purpose Overview

The PEX8616-BB50RBC F is a PCI Express Gen2 switch integrated circuit manufactured by Broadcom Limited. It features 16 lanes and 4 ports with a data rate of 5.0 GT/s. The component utilizes an I2C interface for configuration and management. It is housed in a 324-ball FCBGA package designed for surface mount technology (SMD/SMT). The device operates within a commercial temperature range from -5°C to +85°C. This specific part number is identified as End-of-Life (EOL) and is no longer in active production.

Analog Switches - Special Purpose Feature Summary

• Supports PCIe Gen2 standard with 5.0 GT/s signaling rates across 16 lanes.
• Provides four independent ports for scalable interconnection architectures.
• Enables multi-host configurations with failover capabilities for system redundancy.

Analog Switches - Special Purpose Applications

• Server infrastructure requiring high-bandwidth non-blocking connectivity
• Storage area network (SAN) fabrics and aggregation layers
• Multi-host architecture systems with host failover requirements

Analog Switches - Special Purpose Procurement Notes

This component is officially discontinued and marked as End-of-Life by the manufacturer. Availability is restricted to existing stock or third-party distributors, with no new manufacturing orders accepted. Verification of authenticity and lot traceability is critical when sourcing from secondary markets due to the obsolescence status. Buyers should confirm the exact suffix compatibility and physical condition before acquisition.

Analog Switches - Special Purpose Selection Notes

Designers must account for the discontinuation status when selecting this component for new products. While the electrical specifications remain consistent with the PEX8616 family, the BB50RBC F suffix denotes specific packaging and environmental ratings that may not be interchangeable with other suffixes without verification. Alternative solutions within the PEX87xx series are recommended for long-term supply chain stability.

Analog Switches - Special Purpose Part Context

The PEX8616 belongs to the ExpressLane family of PCIe switches, designed for fan-out and peer-to-peer applications. It serves as a bridge between host processors and peripheral endpoints. The device supports legacy single-host mode as well as multi-host modes with up to five host ports, facilitating clustered system designs and redundant power supplies.

Analog Switches - Special Purpose Replacement Considerations

Broadcom recommends the PEX8724-CA80BC G as a manufacturer-recommended replacement for similar lane counts in the updated portfolio. Other potential substitutes include the PEX8714-AB80BI G and PEX8717-CA80BC G, depending on specific port and lane requirements. These newer models offer enhanced performance and continued availability.
