Product Description
The AX88178 USB to 10/100/1000 Gigabit Ethernet/HomePNA/HomePlug controller is a high performance and highly
integrated ASIC with embedded 40KB SRAM for packet buffering. It enables low cost and affordable Gigabit Ethernet
network connection to desktop and notebook PC using popular USB ports that are built-in to many PC today. It has an
USB interface to communicate with USB host controller and is compliant with USB specification V1.0, V1.1 and V2.0. It
implements 10/100/1000Mbps Ethernet LAN function based on IEEE802.3, IEEE802.3u, IEEE802.3ab standards or
HomePNA standard. It supports media-independent interface (MII) to simplify the design on implementing Fast Ethernet
and HomePNA functions. It also provides gigabit media-independent (GMII) and reduced gigabit media-independent
(RGMII) interface for interfacing with Gigabit Ethernet PHY.
