BCM56026B0KPBG

Overview

The BCM56026B0KPBG is a member of the Broadcom StrataXGS Tomahawk family, designed as a high-performance Ethernet switch ASIC. It supports line-rate switching at 10 Gigabit Ethernet speeds with a non-blocking switching capacity of 384 Gbps. The device integrates 48 ports of 10GbE connectivity and includes an internal buffer memory of 9 Megabits to manage traffic bursts effectively. It utilizes a 0.13-micron process technology and operates within a standard commercial temperature range. The component is housed in a large ball grid array package suitable for dense board layouts.

Feature Summary

• Supports wire-speed packet processing for 10GbE interfaces
• Integrates substantial on-chip memory for advanced buffering
• Enables complex Layer 2 and Layer 3 forwarding functions

Applications

• High-density enterprise core switches
• Service provider edge aggregation platforms
• Data center spine and leaf network architectures

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and thermal specifications. Ensure that the source documentation explicitly identifies the manufacturer as Broadcom Limited or its successor entities. Request detailed test reports to validate signal integrity for high-speed serial interfaces before integration into final designs.

Selection Notes

Evaluate the required port density against the fixed 48-port configuration of this model. Consider the power consumption profile relative to available cooling infrastructure in the target chassis. Confirm that the host system can support the necessary clocking and reset sequencing requirements specified in the hardware design guidelines.

Part Context

This component belongs to the StrataXGS product line, representing a generation of silicon optimized for high-throughput IP routing and switching. It serves as a foundational building block for next-generation networking equipment requiring low latency and high scalability. The part number denotes specific packaging and operational characteristics distinct from other variants in the series.

Replacement Considerations

Direct replacements are limited due to proprietary architecture. Potential alternatives include newer generations from the same vendor or competitive ASICs with comparable port counts. Verify register-level compatibility if migrating software drivers across different silicon revisions.
