BCM56842A1KFRBG

Overview

The Broadcom BCM56842A1KFRBG is a high-performance Ethernet switch chip designed for data center and enterprise core routing applications. It utilizes a 7nm low-power process technology to deliver significant performance density and energy efficiency improvements over previous generations. The device supports advanced PAM4 modulation techniques, facilitating smooth migration paths to higher baud rates such as 800G interfaces. Key specifications include a total switching capacity of 12.8 Tbps and support for up to 32 ports of 400G connectivity. This architecture enables reduced equipment counts and lower total cost of ownership in high-density network deployments.

Feature Summary

• Supports 56G PAM4 high-speed interface signaling for next-generation bandwidth requirements.
• Integrates open SDK compatibility with major Network Operating Systems to accelerate product development cycles.
• Delivers superior power efficiency compared to prior generation devices, aligning with green data center standards.

Applications

• High-density 400G data center spine and leaf switches
• Enterprise core routing infrastructure
• Cloud computing network interconnects

Procurement Notes

Verify the specific suffix KFRBG against the manufacturer's official datasheet to confirm package type and temperature range. Ensure that any ordering suffixes do not alter the functional characteristics unless explicitly documented by the source. Cross-reference the part number with authorized distributors to confirm current availability status and lead times without relying on speculative inventory data.

Selection Notes

Select this component when designing networks requiring 12.8 Tbps throughput with 400G port density. Evaluate thermal management solutions suitable for 7nm process nodes. Confirm software ecosystem compatibility with existing NOS platforms before finalizing the design. Consider the transition path from 100G/200G architectures to ensure backward compatibility where necessary.

Part Context

This model belongs to Broadcom's Trident series of Ethernet switching processors. It represents a generation focused on high-port-count, high-bandwidth applications. The device competes in the segment of ultra-high-performance switching silicon used in large-scale cloud and service provider infrastructures.

Replacement Considerations

Consult official substitution guides for compatible Broadcom series members. Verify pin-to-pin compatibility if replacing legacy models. Ensure firmware and software support alignment for any alternative part numbers within the same product family.
