BCM56526B0KFSBLG

Overview

The BCM56526B0KFSBLG is a high-performance data center switch ASIC from Broadcom's Trident family, designed for scalable Ethernet switching applications. It supports line-rate forwarding with low latency and includes hardware acceleration for network virtualization protocols such as VXLAN and NVGRE. The device integrates programmable packet processing capabilities to allow flexible traffic management and policy enforcement. It features advanced telemetry functions like In-band Network Telemetry (INT) for real-time visibility into network congestion and performance metrics. The component utilizes a flip-chip package suitable for high-density board designs.

Feature Summary

• Hardware-accelerated support for overlay networking protocols including VXLAN, NVGRE, and Geneve.
• Programmable packet processing engine enabling custom forwarding logic and traffic manipulation.
• Integrated In-band Network Telemetry (INT) for granular, per-packet flow monitoring.
• High-throughput architecture optimized for low-latency data center spine and leaf deployments.

Applications

• Data center spine and leaf switches requiring high port density.
• Network infrastructure supporting software-defined networking (SDN) architectures.
• Cloud computing environments needing hardware-accelerated network virtualization.

Procurement Notes

Verify the specific suffix KFSBLG against the manufacturer's official datasheet to confirm pinout compatibility and thermal specifications. Ensure that the required firmware images and SDK versions are available for the intended operating system. Cross-reference the package type and lead time requirements with authorized distributors to align with production schedules. Confirm that the supply chain source provides genuine components with traceability documentation.

Selection Notes

Select this component when designing switches that require robust hardware acceleration for network virtualization overlays. Consider its programmability if custom packet parsing or specialized QoS policies are necessary. Evaluate the power consumption and thermal dissipation requirements associated with the flip-chip package in the target chassis design. Compare its throughput and port count against other members of the Trident family to ensure it meets the specific bandwidth demands of the application.
