BCM56526B0IFSBLG

Overview

The BCM56526B0IFSBLG is a high-performance Ethernet switch integrated circuit manufactured by Broadcom Limited. It belongs to the Trident II family of switching fabrics, designed for core and aggregation layers in data center networks. The device supports advanced packet processing capabilities including Quality of Service (QoS), traffic shaping, and multicast replication. It features a non-blocking architecture with high throughput rates suitable for enterprise and service provider environments. The component integrates multiple physical layer interfaces and provides comprehensive management features for network monitoring and control.

Feature Summary

• Supports high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet port configurations
• Integrates advanced QoS mechanisms for traffic prioritization and congestion management
• Provides hardware-based security features including ACLs and encryption support
• Enables scalable fabric architecture for large-scale data center deployments

Applications

• Data center spine and leaf switch architectures
• Service provider edge routing and switching equipment
• Enterprise core network aggregation switches
• High-performance computing interconnects

Procurement Notes

Verify the exact suffix IFSBLG against official Broadcom documentation to confirm package type and temperature range. Confirm end-of-life status as previous similar models have been discontinued. Request RoHS compliance certificates and material declarations from authorized distributors. Validate authenticity through serial number verification channels provided by the manufacturer.

Selection Notes

Compare pin compatibility and register map differences with existing designs when migrating from older Broadcom switch families. Ensure thermal design accounts for the power dissipation characteristics of the specific package variant. Verify software support availability for the Trident II architecture in current network operating systems. Check interface signal integrity requirements for high-speed SerDes lanes.

Part Context

This component is part of Broadcom's Trident II series, which succeeded earlier generations like the Tomahawk predecessor in certain market segments. It represents a generation of switches focused on balancing port density with low latency performance. The IFSBLG suffix typically denotes a specific ball grid array package configuration intended for high-volume manufacturing processes.

Replacement Considerations

Direct pin-to-pin replacements may not exist due to architectural evolution. Consider Broadcom BCM56840 or BCM56970 series for newer designs. Evaluate software migration paths if substituting within existing infrastructure. Verify that feature parity meets application requirements before selecting alternative components.
