SuperSpeed USB Transceiver with PIPE3 and ULPI Interfaces

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. The PIPE interface controls the TUSB1310 low power states which minimizes power consumption.

SuperSpeed USB leverages existing USB software infrastructure by keeping the existing software interfaces and software drivers. In addition the SuperSpeed USB retains backward compatibility at the Type-A connector with USB2.0 based PCs and with USB2.0 cables.
