BCM56268B0KFSBG

Overview

The BCM56268B0KFSBG is a Broadcom Limited Ethernet IC designed for telecom backhaul access switch applications. It belongs to the Saber2 series, with the B0 suffix indicating the silicon stepping and KFSBG denoting the specific package configuration. The component is classified under communication and networking integrated circuits. It supports RoHS3 compliance and carries an ECCN classification of 5A991C1. The device operates as a standalone switching solution without requiring external PHYs for supported interfaces.

Feature Summary

• Optimized architecture for telecom backhaul access network deployments
• Integrated packet buffering and memory management unit for traffic handling
• Supports standard Ethernet protocols including IPv4 and IPv6 forwarding

Applications

• Telecom backhaul access switches
• Base station aggregation nodes
• Carrier-grade edge networking equipment

Procurement Notes

Verify the exact silicon revision corresponding to the B0 stepping against the target design requirements before procurement. Confirm that the KFSBG package footprint matches the PCB layout specifications. Ensure the supply chain source provides valid authenticity documentation, as this component requires specialized handling due to its high pin count and sensitivity to electrostatic discharge during assembly processes.

Selection Notes

Select this component when designing for fixed-function backhaul switching rather than programmable data plane requirements. Evaluate the thermal dissipation capabilities required for the specific FBGA package in the intended enclosure. Compare against the BCM56262 variant if different port densities or feature sets are needed for the specific access node topology.

Part Context

This part is a member of the Broadcom Saber2 family, which targets cost-effective and power-efficient switching solutions for access networks. It differs from the Tomahawk series by focusing on lower port counts and simpler architectures suitable for edge devices rather than core data center aggregation.

Replacement Considerations

The BCM56262B0KFSBG is a related model within the same product family. Verify pin-to-pin compatibility and software SDK support before considering substitution, as feature sets may vary between specific stepping revisions.
