the tusb1310 is a single port 5.0-gbps usb 3.0 physical layer transceiver operating off of a single crystal or an external reference clock. the reference clock frequencies are selectable from 20 25 30 and 40 mhz. the tusb1310 provides a clock to usb link layer controllers. the single reference clock allows the tusb1310 to provide a cost effective usb 3.0 solution with few external components and a minimum implementation cost. link controller interfaces to the tusb1310 are via a pipe (superspeed) and a ulpi (usb2.0) interface. the 16-bit pipe operates with a 250-mhz interface clock. the ulpi supports 8-bit operations with a 60-mhz interface clock. usb 3.0 reduces active power and idle power by improving power management. view all in datasheet
