BCM56461B0KFSBG

Overview

The BCM56461B0KFSBG is a telecom interface integrated circuit manufactured by Broadcom Limited, belonging to the BCM56460 series. It is designed as a backhaul access switch for telecommunications infrastructure. The component is currently in active production and complies with RoHS3 standards. It utilizes a large-pin-count FBGA package configuration, indicated by the suffix KFSBG, which includes specific silicon stepping and environmental compliance markers. This device serves as a specialized network processor for managing high-density packet forwarding in carrier-grade access networks.

Feature Summary

• Specialized hardware architecture optimized for backhaul access switching applications within telecommunications networks.
• Integrated support for high-speed serial data interfaces required for modern fiber optic transport systems.
• Hardware-accelerated processing capabilities designed to handle complex packet forwarding and protocol termination tasks.

Applications

• Telecommunications backhaul access nodes
• Carrier-grade Ethernet aggregation switches
• Fiber-to-the-x (FTTx) network edge equipment

Procurement Notes

Verify the exact ordering part number against the manufacturer's current datasheet to ensure compatibility with the intended PCB layout and firmware requirements. Confirm that the B0 silicon stepping matches the design specifications. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component specifically for backhaul access scenarios requiring dedicated ASIC performance rather than general-purpose routing. Ensure the system design accommodates the thermal and power requirements associated with high-density FBGA packages. Validate that the software development kit supports the specific feature set needed for the target network topology.

Part Context

This part is a variant within the Broadcom BCM56460 family of telecom switches. The suffix B0KFSBG denotes the specific silicon revision, package type, and environmental compliance status. It shares the core architectural foundation with other members of the series but is distinguished by its specific manufacturing lot and packaging configuration for mass deployment in access networks.

Replacement Considerations

Direct replacements are limited within the same family. Verify if BCM56460B0KFSBG or similar variants offer identical pinouts and functionality. Cross-referencing with the latest Broadcom product selector guide is essential to confirm backward compatibility and feature parity before substituting.
