BCM88370CB0KFSBG

Controllers Overview

The BCM88370CB0KFSBG is a Gigabit Ethernet switch controller from Broadcom's StrataDNX Qumran-MX family. It features 56 NIF Serdes without an integrated fabric, designed for high-density switching applications. The component utilizes a 1365-FCPBGA package measuring 37.5x37.5 mm. It supports Ethernet protocols and operates within industrial temperature ranges. This centralized switch solution provides dedicated interface capabilities for network infrastructure equipment requiring robust Layer 2 switching performance.

Controllers Feature Summary

• Provides 56 NIF Serdes interfaces for high-speed data transmission
• Designed as a centralized switch controller without integrated fabric
• Supports Gigabit Ethernet protocol standards
• Engineered for industrial temperature operation environments

Controllers Applications

• High-density enterprise network switches
• Telecommunications infrastructure equipment
• Industrial networking gateways
• Data center access layer switching systems

Controllers Procurement Notes

Verify the specific suffix KFSBG to confirm the package type and temperature range. Confirm lifecycle status as obsolete or limited supply through official Broadcom channels. Ensure compatibility with existing PCB layouts due to the specific FCBGA footprint requirements. Check for RoHS3 compliance documentation before integration into regulated markets.

Controllers Selection Notes

Select this component when 56 independent NIF Serdes are required without internal fabric switching. Compare against BCM88470 variants if higher throughput or fabric integration is needed. Verify that the 1365-ball BGA package fits the target board design constraints. Ensure the application does not require Layer 3 routing features inherent in other Broadcom series.

Controllers Part Context

This part belongs to the Broadcom StrataDNX Qumran-MX family of Gigabit Ethernet controllers. It serves as a specialized interface solution distinct from the BCM88470 which offers centralized switching with fabric capabilities. The Qumran-MX series focuses on providing extensive serdes connectivity for custom switching architectures.

Controllers Replacement Considerations

The BCM88470CB0KFSBG is a related model but includes fabric capabilities. Direct substitutes may be unavailable due to the obsolete lifecycle status. Consult Broadcom for current equivalent recommendations or updated platform migrations.
