Product Description
AX88179 can be used in any embedded system with a USB host microcontroller requiring a twisted pair physical
network connection. Featuring a USB interface (compliant with USB specification V3.0, V2.0 and V1.1) to
communicate with a USB Host Controller, the AX88179 also integrates on-chip Gigabit Ethernet MAC and PHY
(IEEE802.3, IEEE802.3u and IEEE802.3ab compatible). Additionally, the AX88179 needs only a single 25MHz crystal
to drive both the USB and Ethernet PHYs.
The AX88179 offers a wide array of features including IPv4/IPv6 checksum offload engine, crossover detection and
auto-correction, TCP large send offload and IEEE802.3az EEE (Energy Efficient Ethernet). The EEE defines a
mechanism that allows the AX88179 to enter a low power idle state to reduce power and to achieve a more energy
efficient Ethernet. It supports dynamic cable length detection and dynamic power adjustment Green Ethernet in Gigabit
mode. The AX88179 also offers multiple power management Wake-on-LAN features, including Magic Packet,
Microsoft Wakeup Frame and Link Status Change that allows systems to enter a low power state and wake on desired
network traffic.
