BCM56820B0KFSBG

Overview

The BCM56820B0KFSBG is a Broadcom multilayer Ethernet switch ASIC providing 24 ports of 10-Gigabit Ethernet and four ports of 1-Gigabit Ethernet. It delivers line-rate full-duplex switching for over 240 Gbps with integrated SerDes, packet buffer memory, and PLLs. The device supports flexible port configurations where each 10-GbE port can operate at 1 GbE, 2.5 GbE, or 10 GbE speeds. It features built-in Layer 2/VLAN tables, Layer 3 tables with VRF support, and a multistage ingress/egress ContentAware Engine for deep packet inspection. Advanced traffic management includes IEEE 802.3 Link Pause, Service Aware Flow Control (SAFC), and hardware failover recovery in under 10 microseconds.

Feature Summary

• Multistage ContentAware Engine enables deep packet inspection, classification, and flexible access control lists at line rate.
• Intelligent Traffic Management with SAFC supports storage, HPC, video, voice, and data convergence over unified fabrics.
• Advanced load balancing and ultralow latency provide high-performance solutions for High Performance Computing environments.
• Sixth-generation HiGig/HiGig2 stacking technology facilitates full-speed upgrades while maintaining compatibility with existing deployments.

Applications

• Enterprise aggregation networks requiring high-density 10-GbE connectivity
• Data center applications supporting unified fabric convergence
• High Performance Computing (HPC) environments demanding low latency and fast failover
• Fixed or stackable modular switch designs utilizing HiGig backplane interfaces

Procurement Notes

Verify the specific B0 silicon stepping and KFSBG package configuration against your system requirements before procurement. Confirm that the component meets all necessary environmental standards and RoHS compliance specifications required for your deployment. Ensure that the software SDK version aligns with your intended feature set implementation.

Selection Notes

Select this component when designing systems requiring 24 dedicated 10-GbE ports alongside 1-GbE uplinks within a compact form factor. It is suitable for applications needing advanced L2/L3 tunneling capabilities and strict Quality of Service enforcement via multiple scheduling algorithms. Consider its integration with existing HiGig-based architectures to leverage backward compatibility and simplified upgrade paths.

Part Context

This part belongs to the Broadcom BCM56820 series, which focuses on high-port-density enterprise and data center switching. It serves as a fixed-configuration alternative to modular switch fabric cards, offering comparable performance in a smaller footprint. The device integrates directly with Broadcom's established software API and SDK ecosystem.

Replacement Considerations

The BCM56821 offers an expanded configuration with 48 x 10-GbE and 16 x 1-GbE ports. Evaluate the BCM56821 if higher port density is required for modular switch fabric card applications. Both parts share similar architectural foundations and software compatibility.
