Product Description

The AX88772 USB to 10/100 Fast Ethernet/HomePNA/HomePlug controller is a high performance and highly integrated

ASIC with embedded 28KB SRAM for packet buffering. It enables low cost and affordable Fast 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 V1.1 and V2.0. It implements

10/100Mbps Ethernet LAN function based on IEEE802.3, and IEEE802.3u standards or HomePNA standard. It

integrates an on-chip 10/100Mbps Ethernet PHY to simplify system design and provides an optional media-independent

interface (MII) for implementing Fast Ethernet and HomePNA functions.
