SMSC LAN7500 Gigabit Ethernet Controllers

SMSC LAN7500 Hi-Speed USB 2.0 to 10/100/1000 Gigabit Ethernet controllers provide a high-performance and cost-effective USB to Ethernet connectivity solution. The SMSC LAN7500 Ethernet controller contains an integrated 10/100/1000 Gigabit Ethernet PHY, USB PHY, Hi-Speed USB 2.0 device controller, 10/100/1000 Gigabit Ethernet MAC, TAP controller, EEPROM controller, and a FIFO controller with a total of 32KB internal packet buffering. The LAN7500 includes NetDetach™ technology that allows for up to a 25% reduction in power by enabling the host CPU to enter a low-power state when Ethernet is inactive. It also includes UniClock™ technology that simplifies the clocking scheme and reduces system BOM cost by using a single 25MHz crystal for both USB and Ethernet connectivity. The device supports 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet and implements Control, Interrupt, Bulk-in and Bulk-out USB endpoints. The Ethernet controller supports auto-negotiation, auto-polarity correction, HP Auto-MDIX support and is compliant with IEEE 802.3/802.3u/802.3ab standards. USB-based networking provides flexibility for the routing and placement of network connections anywhere in the system. USB-based solutions leverage the existing USB stack for the Ethernet driver. The SMSC LAN7500 is also available with a wide range of drivers including Windows®, Mac® and Linux® and in commercial (0º to 70ºC) and industrial temperature range (-40º to 85ºC) options.
