BCM56262B0KFSBG

Overview

The BCM56262B0KFSBG is a Layer 3 Ethernet switch ASIC belonging to the Broadcom StrataXGS SABER2 family. It provides a switching capacity of 720 Gbps with a forwarding rate of 540 Mpps. The device integrates 16 ports of 10 Gigabit Ethernet and four ports of 40 Gigabit Ethernet, utilizing a 40 nm process technology. It supports advanced packet processing features including hardware-based ACLs, QoS, and multicast replication.

Feature Summary

• Supports high-density 10G and 40G port configurations for flexible network topology deployment
• Integrates hardware-accelerated security policies and traffic classification mechanisms
• Provides low-latency packet forwarding suitable for enterprise aggregation layers

Applications

• Enterprise core and distribution layer switches
• Data center top-of-rack aggregation
• Service provider edge routing platforms

Procurement Notes

Verify the specific silicon stepping indicated by the suffix B0 against design requirements. Confirm RoHS compliance status through official documentation. Ensure ESD protection protocols are followed during handling due to the fine-pitch FBGA package. Validate that the selected package variant matches the PCB footprint specifications.

Selection Notes

Select this component for designs requiring a balance between 10G and 40G uplink density. Compare against SABER3 series models if higher throughput or additional port counts are necessary. Evaluate power consumption constraints relative to the 40 nm node performance. Ensure thermal management solutions accommodate the package's heat dissipation characteristics.

Part Context

This part belongs to the SABER2 product line, positioned below the Tomahawk series in terms of aggregate bandwidth. It targets mid-range networking equipment where cost-efficiency and moderate port density are prioritized over extreme scale. The B0 designation refers to the specific silicon revision within the BCM56262 family.

Replacement Considerations

Direct replacements include other revisions of the BCM56262 series such as BCM56262A0KFSBG. For upgraded performance, consider the BCM56263 series which offers increased port density.
