ASIX Electronics Corp. debuts a controller that that integrates a USB 3.0 PHY and 10/100/1000Mbps Gigabit Ethernet MAC/PHY in one chip.

The plug-and-play AX88179 comes in a small form factor to enable embedded system designers to deliver Gigabit Ethernet connectivity with the speed of USB 3.0 SuperSpeed technology.


ASIX Electronics' AX88179 integrates a USB 3.0 PHY and 10/100/1000Mbps Gigabit Ethernet MAC/PHY in a small form factor one-chip plug-and-play solution.

The AX88179 can be used in any embedded system with a USB host MCU 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). Also, the AX88179 needs only a single 25MHz crystal to drive both the USB and Ethernet PHYs.

The controller features 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 wake on desired network traffic.

It is supported by a wide range of drivers for the most recent versions of Windows, Mac, Linux and WinCE operating systems. It is suited for desktop PCs, notebooks, ultrabooks, cradles/port replicators/docking stations, game consoles, digital-home appliances, and any embedded system using a standard USB port.

To help customers evaluate and develop applications with the AX88179, ASIX provides comprehensive technical support including hardware and software application notes, user guides, schematics, and PCB layout guides.

The AX88179 is available in an 8mm x 8mm 68-pin Pb-free QFN package. It is RoHS compliant and operates in the 0°C to 70°C temperature range.

Samples are available now with mass production beginning at the end of Q1 12.
