BCM53422A0IFSBG

Overview

The BCM53422A0IFSBG is a high-performance Ethernet switch integrated circuit manufactured by Broadcom Limited. It features an architecture comprising eight 1 Gigabit Ethernet ports and two 10 Gigabit Ethernet SerDes interfaces. The device supports advanced Layer 2 switching capabilities, including VLAN tagging, QoS prioritization, and link aggregation protocols to ensure efficient data handling. Designed for robust network infrastructure, it integrates hardware-based security policies and traffic management functions suitable for demanding enterprise and service provider environments requiring scalable bandwidth.

Feature Summary

• Integrates eight 1G copper ports alongside dual 10G SerDes uplinks for flexible connectivity
• Supports comprehensive Layer 2 switching features including VLANs, QoS, and LACP
• Includes hardware-accelerated security mechanisms such as ACLs for traffic filtering

Applications

• Enterprise core and distribution layer switches
• Service provider edge aggregation platforms
• High-density access point backhaul systems

Procurement Notes

Verify the specific ordering suffix against official Broadcom documentation to confirm package type and temperature range specifications. Ensure compatibility with existing PCB footprints and power delivery networks before procurement. Confirm RoHS compliance status through current manufacturer declarations. Validate supply chain authenticity via authorized distributors to mitigate counterfeit risks.

Selection Notes

Select this component when deploying networks requiring mixed 1G and 10G interface densities within a single chassis. Evaluate thermal dissipation requirements due to the high pin count and processing load inherent in the BGA package. Compare against lower-port-count variants if cost constraints exist, or higher-capacity models if future scalability demands exceed the 8x1G + 2x10G configuration limits.

Part Context

This part belongs to the Broadcom BCM53422 family of Ethernet switches, designed for scalable networking solutions. It shares architectural similarities with other members like the BCM53416 but offers distinct port configurations tailored for specific throughput needs. The series emphasizes integration of switching logic with control plane efficiency for modern IP networks.

Replacement Considerations

Direct substitutes include the BCM53422A0KFSBG, which may differ primarily in packaging or temperature grading rather than functional logic. Verify pin-to-pin compatibility and electrical characteristics before substitution. Consult Broadcom's cross-reference guides for approved alternative components within the same product line.
