BCM56800SAB01

Overview

The BCM56800SAB01 is a high-performance multilayer switch chip from Broadcom's Tomahawk series, designed for enterprise and data center core routing applications. It delivers a switching capacity of 3.2 Tbps with a packet processing rate of 2.4 billion packets per second (Bpps). The device features 32 ports supporting 10 Gigabit Ethernet and HIGIG2 interfaces, enabling dense connectivity for spine switches in Clos architectures. It integrates advanced hardware-based quality of service (QoS) mechanisms, including traffic classification, policing, and scheduling, to ensure deterministic latency and low jitter for critical network traffic.

Feature Summary

• Supports non-blocking wire-speed forwarding across all 32 ports simultaneously
• Integrates hardware-accelerated QoS for complex traffic prioritization and shaping
• Provides scalable architecture suitable for high-density spine layer deployments

Applications

• Core and aggregation layer switches in enterprise campus networks
• Spine switches in data center Clos fabric topologies
• High-throughput router platforms requiring multi-layer switching capabilities

Procurement Notes

Verify the specific suffix 'SAB01' against the official Broadcom datasheet to confirm package type, temperature range, and revision level. Ensure compatibility with existing board designs regarding pinout and power requirements before procurement.

Selection Notes

Select this component when a 3.2 Tbps switching fabric is required for 10GbE/HIGIG2 environments. Compare against the BCM56801 or BCM56802 if port counts differ, ensuring the 32-port configuration aligns with the target system density and throughput needs.

Part Context

This part belongs to the Broadcom Tomahawk family, specifically positioned as a high-capacity multilayer switch solution. It serves as a foundational component for building scalable network infrastructure that demands high bandwidth and low latency performance.

Replacement Considerations

Direct substitutes include other variants within the BCM56800 series such as the BCM56801 or BCM56802, depending on the required port count and interface mix. Verify functional equivalence and pin compatibility before substitution.
