BCM56822B0KFSBLG

Overview

The BCM56822B0KFSBLG is a high-performance Ethernet switch integrated circuit manufactured by Broadcom Limited. It belongs to the BCM5682x family of multi-layer switching solutions designed for carrier-class access and aggregation networks. The device features a non-blocking switching fabric capable of handling high throughput with low latency, supporting advanced Quality of Service (QoS) and security policies. It integrates multiple Gigabit Ethernet ports and high-speed serial interfaces for uplink connectivity, enabling flexible deployment in dense network environments while maintaining robust packet processing capabilities.

Feature Summary

• Supports multi-layer switching operations including Layer 2 bridging, Layer 3 routing, and MPLS forwarding functions.
• Integrates hardware-accelerated QoS mechanisms for traffic prioritization, policing, and shaping across all ports.
• Provides comprehensive security features such as ACLs, MAC filtering, and encryption support for data protection.

Applications

• Carrier-grade DSLAM and GPON OLT aggregation platforms
• Metro Ethernet access switches for service provider networks
• High-density enterprise core or distribution layer switches

Procurement Notes

Verify the exact ordering suffix against the official Broadcom datasheet to ensure correct package type, temperature range, and lead-free status. Confirm RoHS compliance and REACH registration status prior to procurement. Check for any active Product Change Notifications (PCNs) that may affect pin compatibility or material composition. Ensure supply chain authenticity through authorized distributors only.

Selection Notes

Select this component when designing systems requiring scalable multi-layer switching with integrated QoS and security. Compare port density and interface types against alternative models in the BCM568xx series. Evaluate thermal management requirements based on the specific package variant. Ensure host processor compatibility with the control interface specifications provided in the technical reference manual.
