BCM56226B0KPBG

Overview

The BCM56226B0KPBG is a member of the Trident II family, designed as a high-performance Ethernet switch ASIC for data center and enterprise core routing applications. It supports a switching capacity of 1.44 Tbps with a packet buffer of 3.6 Mbits. The device integrates 24 ports of 10 Gigabit Ethernet and four ports of 40 Gigabit Ethernet. It features advanced Quality of Service (QoS) capabilities, including hardware-based traffic classification and scheduling. The component operates within a standard industrial temperature range and utilizes a large plastic ball grid array package to accommodate the high pin count required for extensive I/O connectivity.

Feature Summary

• Supports non-blocking switching fabric architecture for high-throughput data forwarding
• Integrates comprehensive QoS mechanisms for strict latency and jitter control
• Provides hardware-accelerated multicast replication for efficient broadcast handling
• Includes built-in security features such as ACLs and encryption offload

Applications

• Data center spine and leaf switches
• Enterprise core network routers
• Service provider edge aggregation platforms

Procurement Notes

Verify the specific suffix 'B0K' against the manufacturer's official datasheet to confirm voltage levels and temperature grades. Ensure compatibility with existing PCB layouts regarding the BGA footprint and thermal requirements. Request original manufacturer documentation to validate authenticity and traceability before finalizing any acquisition.

Selection Notes

Compare this model against newer Trident III or Tomahawk series devices if higher port densities are required. Evaluate power consumption specifications relative to cooling constraints in the target enclosure. Confirm that the supported Ethernet speeds align with the upstream and downstream network infrastructure requirements.

Part Context

This component belongs to Broadcom's Trident II family, which established a benchmark for 10G/40G switching performance. It succeeded earlier generations by offering improved density and lower power per gigabit. The part is widely recognized in telecommunications and cloud computing infrastructure for its reliability and feature set.

Replacement Considerations

Direct pin-to-pin replacements are generally unavailable due to architectural differences. Consider Broadcom BCM56840 or BCM56970 series for functional equivalents with updated feature sets. Verify software driver support and register compatibility when migrating to alternative silicon.
