高速度的USB 2.0至10/100/1000以太网控制器LAN7500/LAN7500i数据表

　　The LAN7500/LAN7500i is a high performance Hi-Speed USB 2.0 to 10/100/1000 Ethernet controller. With applications ranging from embedded systems， set-top boxes， and PVR’s， to USB port replicators， USB to Ethernet dongles， and test instrumentation， the device is a high performance and cost competitive USB to Ethernet connectivity solution. The LAN7500/LAN7500i contains an integrated 10/100/1000 Ethernet MAC and PHY， Filtering Engine， USB PHY， Hi-Speed USB 2.0 device controller， TAP controller， EEPROM controller， and a FIFO controller with a total of 32 KB of internal packet buffering. The internal USB 2.0 device controller and USB PHY are compliant with the USB 2.0 Hi-Speed standard. The device implements Control， Interrupt， Bulk-in， and Bulk-out USB Endpoints. The Ethernet controller supports auto-negotiation， auto-polarity correction， HP Auto-MDIX， and is compliant with the IEEE 802.3， IEEE 802.3u， IEEE 802.3ab standards. ARP and NS offload is also supported. Multiple power management features are provided， including various low power modes and “Magic Packet”， “Wake On LAN”， and “Link Status Change” wake events. These wake events can be programmed to initiate a USB remote wakeup. An internal EEPROM controller exists to load various USB configuration information and the device MAC address. The integrated IEEE 1149.1 compliant TAP controller provides boundary scan via JTAG.
