Product description
The AX88172 USB to Fast Ethernet/HomePNA/HomePlug Controller is a high performance and highly integrated
Controller with embedded 7K*16 bit SRAM. The AX88172 contains a USB interface to host CPU and compliant with
USB Standard V1.0, V1.1 and V2.0. The AX88172 could be used for both 10M/100Mbps Fast Ethernet function based on
IEEE802.3 / IEEE802.3u LAN standard and 1M/10M HomePNA standard. The AX88172 supports media-independent
interface (MII) to simplify the design on implementing Fast Ethernet and HomePNA functions.
