BCM56274A1KFSBG

Overview

The BCM56274A1KFSBG is a Broadcom Ethernet switch integrated circuit designed for high-density Gigabit Ethernet applications. It features a 48-port GE switching fabric with 24 integrated PHYs, enabling compact board designs by eliminating external transceivers for copper connections. The device supports MACsec encryption for data security and operates within a commercial temperature range of 0°C to 85°C. Packaged in an FCBGA format, it utilizes a 16nm process technology to deliver efficient power consumption relative to throughput.

Feature Summary

• Integrates 48 Gigabit Ethernet ports with 24 built-in physical layer transceivers for reduced component count
• Supports MACsec hardware acceleration for link-layer data confidentiality and integrity protection
• Utilizes 16nm CMOS process technology to optimize power efficiency per bit of throughput

Applications

• High-density enterprise access and aggregation switches
• Telecommunications edge routing platforms requiring integrated PHY solutions
• Industrial networking equipment needing secure, compact switching architectures

Procurement Notes

Verify the specific suffix KFSBG against official Broadcom documentation to confirm package type, pinout, and thermal specifications. Ensure compatibility with existing PCB layouts regarding the FCBGA footprint. Confirm that the commercial temperature rating (0°C to 85°C) meets the operational requirements of the target deployment environment before finalizing procurement.

Selection Notes

Select this component when a dense Gigabit Ethernet solution with integrated copper PHYs is required to minimize bill of materials. It is suitable for designs prioritizing MACsec compliance without adding separate security coprocessors. Consider the 16nm process benefits for power-constrained environments compared to older generation switching ASICs lacking integrated physical layers.

Part Context

This part belongs to Broadcom's portfolio of communication and networking ICs, specifically targeting the Ethernet switch subcategory. It complements other Broadcom silicon by offering a specialized configuration focused on Gigabit speeds rather than the multi-terabit throughput found in the Tomahawk series. The integration of MACsec and PHYs distinguishes it from pure switching fabric controllers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate cross-compatibility only through direct comparison of pinouts, electrical characteristics, and software support matrices with current inventory.
