BCM56270A0KFEBG

Overview

The BCM56270A0KFEBG is a Broadcom Ethernet switch integrated circuit designed for carrier-grade networking applications. It features a port configuration of four 2.5 Gigabit Ethernet ports, four 10 Gigabit Ethernet ports, and four 10 Gigabit Ethernet ports supporting both standard and high-gain variants. The device supports stacking capabilities via its 10 Gigabit interfaces to facilitate scalable network architectures.

Feature Summary

• Integrates mixed-speed Ethernet interfaces including 2.5GE, 10GE, and 10GE/HG ports on a single chip
• Supports stacking functionality through dedicated 10 Gigabit Ethernet connections for expanded topology
• Designed for carrier switch implementations requiring high-density port configurations

Applications

• Carrier Ethernet switching infrastructure
• Network aggregation layers requiring mixed speed ports
• Stacked switch fabric deployments

Procurement Notes

Verify component authenticity through authorized Broadcom distribution channels or certified partners. Confirm RoHS compliance status and current lifecycle stage prior to integration. Request official datasheets and product change notifications to ensure design continuity. Validate package markings against manufacturer specifications to prevent counterfeit substitution.

Selection Notes

Select this component when designing systems requiring a specific combination of 2.5 Gigabit and 10 Gigabit Ethernet interfaces within a single silicon solution. Evaluate thermal management requirements for the BGA package. Ensure PCB layout supports the necessary pin counts and signal integrity for high-speed serial interfaces. Consider stacking port availability if network expansion is planned.

Part Context

This part belongs to Broadcom's portfolio of Ethernet switch integrated circuits targeting communication and networking sectors. It serves as a specialized solution for carrier environments where diverse port speeds are required without multiple discrete controllers. The device complements broader switch families by offering a focused port count and interface mix.

Replacement Considerations

Consult official Broadcom documentation for qualified substitute part numbers with compatible pinouts and electrical characteristics. Verify that alternative components support the same 2.5GE and 10GE interface combinations. Ensure software compatibility and feature parity before implementing any cross-reference.
