BCM56842A1KFTBLG

Overview

The BCM56842A1KFTBLG is a high-performance, single-chip Ethernet switch fabric designed for data center and enterprise core routing applications. It features a non-blocking switching capacity of 3.84 Tbps with a packet buffer memory of 96 Mbits. The device integrates 40 Gigabit Ethernet (40GbE) ports and supports advanced Quality of Service (QoS) mechanisms including strict priority queuing and weighted fair queuing. It utilizes the Trident II architecture to provide low latency and wire-speed forwarding capabilities for complex network topologies.

Feature Summary

• Integrates a high-density switching fabric capable of handling multi-gigabit traffic flows without blocking.
• Supports comprehensive Layer 2 and Layer 3 protocol acceleration for efficient routing and bridging operations.
• Includes integrated hardware-based security features for access control and traffic filtering.

Applications

• Data center spine and leaf switch architectures
• Enterprise core and distribution layer routers
• Service provider edge aggregation platforms

Procurement Notes

Verify the specific suffix 'KFTBLG' against the manufacturer's official datasheet to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing board designs regarding pinout and power requirements before procurement.

Selection Notes

Select this component for designs requiring high port density and low latency in core networking equipment. Evaluate thermal management solutions due to the high power consumption associated with full-throughput switching at 40 Gbps speeds across multiple ports.

Part Context

This part belongs to Broadcom's Trident II family of Ethernet switches, which are widely adopted in high-speed networking infrastructure. It serves as a critical component for scaling bandwidth in modern cloud computing environments and large-scale enterprise networks.

Replacement Considerations

Consult official Broadcom documentation for direct pin-to-pin or functional equivalents within the Trident series. Verify that any substitute maintains support for required 40GbE interfaces and packet buffer sizes.
