focus2009

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, notebook PC, and embedded system using popular USB ports. 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.
