The device supports advanced L2+ features including VLANs, QoS, and link aggregation for enterprise network environments. It is designed for high-density access layer deployments requiring manageable connectivity. The component operates within standard industrial temperature ranges and utilizes a lead-free package compliant with RoHS directives.

Feature Summary

• Supports Layer 2+ managed switching capabilities for enterprise traffic control
• Integrates 24 Gigabit Ethernet ports for end-user connectivity
• Includes four 10 Gigabit Ethernet uplink ports for high-speed aggregation

Applications

• Enterprise campus access layer switches
• High-density wired LAN infrastructure
• Managed network edge devices

Procurement Notes

Verify the specific silicon revision indicated by the B0 suffix against the target design requirements. Confirm that the KFSBG package variant matches the PCB footprint and thermal management strategy. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and compliance status before integration into production systems.

Selection Notes

Select this component when a managed solution with mixed speed ports is required. It serves as an alternative to the BCM53440 series which may offer different port configurations or feature sets. Evaluate the need for L2+ functionality versus basic L2 switching to ensure cost-effectiveness. Consider the physical interface requirements of the 10G uplinks for backplane or cable connections.

Part Context

This part belongs to the Broadcom BCM5344x family of Ethernet switch controllers. It shares architectural similarities with other members like the BCM53440 but offers specific port mapping for 24G + 4XGE configurations. The family targets the enterprise managed switch market, providing a balance of performance and manageability for modern network deployments.

Replacement Considerations

The BCM53440B0KFSBG is a related model within the same product family. Verify if the specific port count or feature set differences between the BCM53442 and BCM53440 variants meet the design specifications before substituting.
