AX88179 is a USB 3.0 to Gigabit Ethernet controller which integrates USB 3.0 PHY and 10/100/1000Mbps Gigabit Ethernet MAC/PHY in a single chip. The AX88179 is the latest addition to ASIX's USB-to-LAN product portfolio, providing a small form factor solution and plug-and-play usability, enabling embedded system designers to deliver Gigabit Ethernet connectivity while leveraging the growth and speed of USB 3.0 SuperSpeed technology.
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.
The AX88179 is a high performance and highly integrated ASIC which enables a low cost, small form factor, and simple plug-and-play Gigabit Ethernet network connection capability for desktops, notebook PCs, ultrabooks, cradles/port replicators/docking stations, game consoles, digital-home appliances, and any embedded system using a standard USB port.
