The LAN9730 is a high-performance, small form factor solution for USB to 10/100 Ethernet port bridging. With applications ranging from embedded systems, set-top boxes, and PVRs, to USB port replicators and test instrumentation, the LAN9730 is targeted as a high-performance, low-cost USB/Ethernet connectivity solution.
The LAN9730 contains an integrated 10/100 Ethernet PHY, HSIC interface, Hi-Speed USB 2.0 device controller, 10/100 Ethernet MAC, TAP controller, EEPROM controller, and a FIFO controller with a total of 30 kB of internal packet buffering. The LAN9730 complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocol and USB 2.0 specification, enabling compatibility with industry standard Fast Ethernet and USB 2.0 applications. The HSIC interface is compliant with the High-Speed Interchip USB Electrical Specification 1.0. High-Speed Inter-Chip (HSIC) is a digital interconnect bus that enables the use of USB technology as a low-power chip-to-chip interconnect at speeds up to 480 Mb/s.
The EVB-LAN9730-MII is an Evaluation Board (EVB) that utilizes the LAN9730 to provide a fully functional, self-powered HSIC to Ethernet interface. The EVB-LAN9730-MII provides fully integrated Ethernet and HSIC interfaces via the onboard RJ45 and HSIC Data/Strobe coaxial connectors. The EVB-LAN9730-MII supports internal and external PHY modes. An external PHY may be connected via the onboard 40-pin female MII connector. The onboard 256x8 EEPROM is used to load the EVBLAN9730-MII's USB configuration parameters and MAC address.
EVB-LAN9730-MII software drivers are available for Windows® XP, Windows Vista, Mac® OS X, Linux®, and Windows CE. Additional manufacturing and diagnostic tools are available for debugging and external EEPROM configuration.
