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.
Device features include an 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 w ake on desired network traffic. Supporting the commercial (0 to 70°C) temperature range, the lead-free, RoHS compliant AX88179 comes in a 8x8mm 68-pin QFN package.
