Asix Electronics has brought out the AX88760, a USB 2.0 MTT Hub and USB 2.0 to Ethernet Combo Controller, the latest member of its high-speed USB-to-LAN controller family.

The AX88760 integrates a USB to Ethernet and three-port USB hub in a single-chip solution.

It provides a small form-factor solution that enables embedded-system designers to design compact, low power, high performance yet low cost applications such as desktops, notebook PCs, ultra-mobile PCs, docking stations, game consoles, multifunction printers, digital-home appliances and any embedded system that uses a standard USB port.

Recent innovations in multimedia SoCs have utilised shrinking physical form factors to reduce costs.

The most efficient method of miniaturisation is to reduce pin count and use a serial interface such as USB, allowing the use of a USB-to-LAN solution, as opposed to a parallel local/memory bus.

By combining the AX88760 with a USB host microcontroller, designers can provide Ethernet and multi-port USB connectivity for embedded systems to control remotely over a network and expand USB ports.

The AX88760’s integrated USB hub complies with the USB 2.0 specification and supports low-speed, full-speed, and high-speed downstream devices on all of the enabled downstream ports.

The AX88760 implements multiple TT (Transaction Translator) architecture, which provides dedicated TT to each downstream (DS) port, which guarantees full-speed (FS) data passing bandwidth when multiple FS devices perform heavy loading operations.

The AX88760 integrates on-chip fast Ethernet MAC and PHY, which is IEEE802.3 10Base-T and IEEE802.3u 100Base-TX compatible, and 24KB embedded SRAM for packet buffering to accommodate high-bandwidth applications.

The AX88760 has a wide array of features, including support for HP Auto-MDIX, Wake-on-LAN power management, and IEEE 802.3x and backpressure flow control.

To help customers evaluate and develop applications with the AX88760, ASIX provides comprehensive technical support, including hardware and software application notes, user guides, schematics, PCB layout guides, and drivers for Windows/Linux/WinCE/MacOS operating systems.

In addition, ASIX has already received complete USB-IF, WHQL and RoHS compliant certifications for the AX88760.
