Product description
The AX88170 USB to Fast Ethernet/HomePNA Controller is a high performance and highly integrated Controller with
embedded 5K*16 bit SRAM. The AX88170 contains a USB interface to host CPU and compliant with USB StandardV1.0 and
V1.1. The interface between AX88170 and PC Host is compliant with USB Communication Class Specification 1.0. The
AX88170 could be used for both 10M /100Mbps Fast Ethernet function based on IEEE802.3 / IEEE802.3u LAN standard and
1M/10M HomePNA standard. The AX88170 supports media -independent interface (MII) or RMII (Reduce MII) interface to
simplify the design on implementing Fast Ethernet and HomePNA functions. The chip also provides an optional MII/RMII
interface with PHY mode, combine with Ethernet repeater or switch IC can build a multiple ports USB-to-USB bridge
application.
