BCM88552B1KFSBLG

Overview

The Broadcom BCM88552B1KFSBLG is a high-performance Ethernet switch integrated circuit designed for data center and enterprise networking applications. It supports 40 Gigabit Ethernet (40GbE) interfaces, enabling high-bandwidth connectivity for server aggregation and core switching roles. The device integrates advanced Quality of Service (QoS) mechanisms, including traffic classification, scheduling, and congestion management features to ensure deterministic latency and packet prioritization. It supports standard Ethernet frame sizes up to jumbo frames, facilitating efficient large-packet transmission. The component utilizes a robust switching fabric architecture to maintain line-rate performance across all ports while minimizing power consumption relative to throughput.

Feature Summary

• Supports 40 Gigabit Ethernet interface speeds for high-throughput network environments
• Integrates comprehensive Quality of Service (QoS) capabilities for traffic prioritization and congestion control
• Features hardware-accelerated packet processing to maintain line-rate switching performance
• Designed for low-latency data transfer in enterprise and data center switching architectures

Applications

• Data center spine and leaf switch aggregation nodes
• Enterprise core and distribution layer switching equipment
• High-performance server-to-switch interconnects requiring 40GbE bandwidth
• Telecommunications infrastructure requiring deterministic latency and QoS

Procurement Notes

Verify the specific suffix B1KFSBLG against official Broadcom documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing PCB footprints and thermal design specifications before procurement. Confirm supply chain authenticity through authorized distributors only.

Selection Notes

Select this component when 40GbE port density and advanced QoS are required. Evaluate power budget constraints as high-speed switching ICs generate significant heat. Compare against newer generation switches if future-proofing or lower latency requirements exist. Verify software support for configuration and management protocols.

Part Context

This part belongs to Broadcom's Trident series of Ethernet switching solutions, which are widely adopted in high-end networking infrastructure. The BCM88552 variant specifically targets 40GbE applications, distinguishing it from 10GbE or 100GbE family members. It represents a mature technology node within Broadcom's portfolio for scalable switching designs.

Replacement Considerations

Check for direct pin-compatible upgrades within the Trident family. Newer generations may offer higher port counts or different interface speeds. Ensure firmware and driver support availability for any substitute components.
