BCM56760B0KFSBG

Overview

The BCM56760B0KFSBG is a high-performance Ethernet switch integrated circuit manufactured by Broadcom Limited. It belongs to the StrataXGS Tomahawk series and provides a switching capacity of 720 Gbps. The device supports multiple Ethernet speeds including 10 Gigabit, 40 Gigabit, and 100 Gigabit interfaces. It is designed for use in enterprise and data center networking environments requiring scalable Layer 2 and Layer 3 switching capabilities.

Feature Summary

• Supports flexible port configurations across 10G, 40G, and 100G Ethernet standards
• Integrates hardware acceleration for advanced network protocols
• Designed for high-density switching applications in modern network infrastructure

Applications

• Enterprise core and distribution layer switches
• Data center top-of-rack (ToR) switching
• High-performance aggregation networks

Procurement Notes

Verify the specific silicon revision indicated by the B0 suffix against your design requirements. Confirm that the KF package type matches your PCB footprint and thermal management strategy. Ensure compatibility with the required SDK version for intended protocol support. Check current availability status as supply levels may fluctuate. Validate RoHS compliance documentation for environmental regulations.

Selection Notes

Select this component when a 720 Gbps switching fabric is sufficient for the target application. Consider it for designs requiring mixed 10G/40G/100G port densities. Evaluate power consumption constraints relative to larger Tomahawk family members. Ensure the host processor can manage the control plane requirements effectively.

Part Context

This part is a member of the Broadcom StrataXGS Tomahawk family, which represents a generation of high-throughput switching ASICs. The BCM56760 variant sits below higher-capacity models like the BCM56960 in terms of total bandwidth. It shares architectural similarities with other chips in the series but offers a specific performance tier suited for mid-range to high-end deployments.

Replacement Considerations

Direct pin-to-pin replacements are generally not available within the same package for different capacities. Upgrades typically require moving to higher-tier models such as the BCM56960 series, which involves significant redesign. Downgrades may involve older generations with lower throughput.
