The AX88760 is a high performance and highly integrated USB/Ethernet and USB/USB connectivity solution which contains an USB 2.0 hub, three downstream USB 2.0 transceivers, an upstream USB 2.0 transceiver, a 10/100M Ethernet PHY, a 10/100M Ethernet MAC, a EEPROM controller, and a 24KB SRAM. The AX88760 is targeted for many applications such as desktops, notebook PCs, Ultra-Mobile PCs, docking stations, game consoles, multifunction printers, digital-home appliances, and any embedded systems using a standard USB port.
Recent innovations in multimedia SoCs have utilized shrinking physical form factors to reduce costs. The most efficient method of miniaturization is to reduce pin count and use a serial interface like 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 is fully compliant with 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 architecture that provides dedicated TT to each downstream (DS) ports, which guarantee Full-Speed (FS) data passing bandwidth when multiple FS device perform heavy loading operations. The AX88760 provides full hub features such as (1) One suspend LED indicator and three downstream port status LED indicators, (2) Individual/Gang mode power management scheme and over-current detection for downstream ports, and (3) Non-removable declaration configured by I/O pin during power-on reset...etc

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
