Overview

AX88179 is the world's first USB 3.0 to Gigabit Ethernet controller which integrates USB 3.0 PHY and 10/100/1000Mbps Gigabit Ethernet MAC/PHY in a single chip. The AX88179 is the latest addition to ASIX's USB-to-LAN product portfolio, providing a small form factor solution and plug-and-play usability, enabling embedded system designers to deliver Gigabit Ethernet connectivity while leveraging the growth and speed of USB 3.0 SuperSpeed technology.

The AX88179 is a high performance and highly integrated ASIC which enables a low cost, small form factor, and simple plug-and-play Gigabit Ethernet network connection capability for desktops, notebook PCs, ultrabooks, cradles/port replicators/docking stations, game consoles, digital-home appliances, and any embedded system using a standard USB port.
