BCM56276A1KFSBG

Overview

The BCM56276A1KFSBG is a Gigabit Ethernet switch integrated circuit manufactured by Broadcom Limited. It integrates 24 front-panel Gigabit Ethernet copper ports, designed for high-density connectivity in enterprise and data center environments. The device supports standard IEEE 802.3 specifications for 10/100/1000BASE-T operation. It features a power budget typically ranging from 12 to 15 watts per port under full load conditions. The component utilizes a fine-pitch ball grid array (FBGA) package suitable for surface-mount assembly.

Feature Summary

• Integrates 24 dedicated Gigabit Ethernet copper front-panel ports
• Supports standard 10/100/1000BASE-T Ethernet protocols
• Optimized power consumption profile with defined per-port thermal limits

Applications

• Enterprise network aggregation switches
• Data center access layer switching
• High-density server connectivity solutions

Procurement Notes

Verify the specific RoHS compliance status and lifecycle stage through official Broadcom documentation or authorized distributor channels before procurement. Confirm that the required factory pack quantity aligns with production volume requirements. Ensure that the PCB design accommodates the FBGA package thermal and mechanical constraints specified in the datasheet. Cross-reference the manufacturer part number with current supply chain notifications to avoid obsolescence risks.

Selection Notes

Select this component when a solution requiring 24 independent Gigabit copper ports is necessary without external PHY complexity. Consider the per-port power budget and total thermal dissipation capabilities relative to the enclosure design. Evaluate compatibility with existing switch ASIC families if system-wide standardization is required. Verify support for required management protocols and software features against the specific application needs.

Part Context

This part belongs to the Broadcom BCM56xxx series of Ethernet switching integrated circuits. These components are widely used in networking infrastructure to provide scalable Layer 2/Layer 3 switching capabilities. The BCM56276A1KFSBG specifically targets applications requiring dense copper connectivity, distinguishing it from fiber-centric or higher-speed multi-gigabit variants within the broader product portfolio.

Replacement Considerations

Consult official Broadcom substitution guides for verified alternative part numbers. Generic cross-references are not recommended due to pinout and feature differences.
