Ethernet Controllers

Integrated circuits that manage wired network communication

An Ethernet controller IC handles the data-link and physical-layer functions required to send and receive packets over a wired network. These chips manage frame buffering, collision detection, and media access control, offloading network processing from the host CPU so the rest of the system can focus on its primary tasks. An Ethernet switch controller IC takes this further by directing traffic across multiple ports, making them central to managed switches and embedded networking equipment. We list Ethernet controller ICs from major manufacturers, so you can compare the latest distributor pricing, check availability, and download datasheets directly from our interface ICs category.
