Broadcom

Overview

Broadcom is a leading semiconductor company whose switching ASICs (Tomahawk, Jericho, Ramon families) underpin a large share of data center Ethernet networking infrastructure. In the AI data center space, Broadcom's silicon powers both the leaf and spine layers of GPU cluster fabrics, with products spanning from low-latency shallow-buffer switches (Tomahawk) for cost-optimized multi-plane architectures to deep-buffer cell-fabric switches (Jericho/Ramon) for traditional fat-tree topologies.

Broadcom's Tomahawk 6 ASIC enables the latest generation of 1.6T Ethernet switches from multiple OEMs, while its Jericho3-AI and Ramon3 silicon powers Meta's DSF (Disaggregated Scheduled Fabric) in the Prometheus gigawatt-scale cluster.
