BCM88361A0KFSBG

Overview

The BCM88361A0KFSBG is a high-performance Ethernet switch fabric chip from Broadcom's Trident series, designed for data center core and aggregation layers. It delivers a switching capacity of 25.6 Tbps with a packet buffer of 48 Mbits. The device supports up to 64 ports of 400G or 128 ports of 200G connectivity. It integrates advanced QoS features, including deep packet buffering and headroom management, to minimize latency and prevent packet loss under heavy load. The component utilizes a 7nm process node for improved power efficiency and density.

Feature Summary

• Supports high-density 400G and 200G port configurations for scalable network architectures.
• Integrates large packet buffer memory to handle traffic bursts and reduce congestion.
• Provides hardware-accelerated quality of service for deterministic latency performance.

Applications

• Data center spine and leaf switches
• High-performance computing interconnects
• Cloud infrastructure aggregation layers

Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to confirm package type, temperature range, and lead time requirements. Ensure compatibility with existing board designs regarding pinout and power delivery specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring non-blocking switching at 25.6 Tbps. Evaluate thermal management solutions due to the high integration density. Confirm software support availability for the intended network operating system environment.

Part Context

This part belongs to the Broadcom Trident family of Ethernet switch fabrics. It represents a generation focused on high throughput and low latency for modern data centers. It complements lower-port-count access switches by providing core-level aggregation capabilities.

Replacement Considerations

Check for backward-compatible upgrades within the same product family. Verify pin-to-pin compatibility if substituting in existing designs. Consult official cross-reference guides for validated alternative part numbers.
