smscs LAN7500 is a hi-speed usb 2.0 to 10/100/1000 gigabit ethernet controller providing a high-performance and cost- effective usb to ethernet connectivity solution. the LAN7500 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 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 fexibility 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 LAN7500 is also available with a wide range of drivers including windows ? , mac ? and linux ? . the LAN7500 also offers smscs netdetach? and uniclock? technologies. netdetach allows for up to a 25% reduction in power by enabling the host cpu to enter a low-power state when ethernet is inactive. uniclock simplifes the clocking scheme and reduces system bom cost by using a single 25mhz crystal for both usb and ethernet connectivity. multiple power management features are provided, including various low-power modes and magic packet?, wake-on lan (wol) and link status change wake events. these wake events can be programmed to initiate a usb remote wakeup. the device is available in commercial (0o to 70oc) and industrial temperature range (-40o to 85oc) options. smscs complimentary and confdential lancheck ? and usbcheck tm online design review services are available for customers who have selected our products for their application design-in**. single-chip, hi-speed usb 2.0 to 10/100/1000 gigabit ethernet controller implements netdetach technology for reduced system power consumption supports eeprom-less operation for reduced bom costs requires only a single 25mhz crystal easy upgrade for usb-based 10/100 ethernet (lan9500/9500a) to 10/100/1000 gigabit ethernet supports ieee 802.3/802.3u/802.3ab standards industrial temperature range option available (LAN7500i) 8x8mm, 56-pin qfn, lead-free rohs-compliant package embedded systems consumer electronics devices netbooks/smartbooks/mids docking stations digital tvs (dtvs) set-top boxes personal video recorders (pvrs) network printers usb port replicators stand-alone usb to ethernet dongles industrial designs target applications highlights LAN7500 hi-speed usb 2.0 to 10/100/1000 gigabit ethernet controller www.smsc.com
