SuperSpeed USB Four-Port Extensible Host Controller with USB-IF Certification

Mon, 04/11/2011 - 9:44am
  Texas Instruments Incorporated (TI) today announced that it is the first semiconductor company to receive certification from the USB Implementer’s Forum (USB-IF) for its SuperSpeed USB (USB 3.0) four-port extensible host controller (xHCI). In addition to the four-port host controller, the TUSB7340, TI also achieved certification for its two-port host controller, the TUSB7320.

These four- and two-port host controllers support such applications as notebooks, desktop computers, workstations, servers, add-in cards and ExpressCard implementations, as well as PCIe-based embedded host controllers for HDTVs, set top boxes and gaming console applications.

TI continues to expand the industry’s broadest portfolio of end-to-end SuperSpeed USB devices with products like these four- and two-port host controllers in addition to existing peripherals, transceivers, hub controllers, redrivers, power switches and ESD protection chips.

Host controller key features and benefits include:

* Certified and compliant: USB-IF and Microsoft’s Windows Hardware Qualification Laboratory (WHQL) standards ensure an open solution for interoperability with industry-wide peripherals and hubs for SuperSpeed USB.

* Sensitivity: Receiver sensitivity of less than 50 mV differential peak-to-peak is twice as good as that required by the USB 3.0 specification, which allows better detection of weak signals for use with longer cables and eases board layout challenges.

* Reduced BOM: Full state-machine architecture eliminates the need for any external storage device, such as EEPROM or Flash, saving bill of materials (BOM) costs by five percent compared to competitive solutions.

TI offers a variety of free tools and support to speed development with TI’s TUSB7340 and TUSB7320:

* TUSB7340EVM evaluation module

* TUSB7340 and TUSB7320 IBIS models

  * Four-port SuperSpeed USB xHCI PCIe Card Hardware Reference Design.

These USB-IF-certified SuperSpeed USB host controllers come in a compact WQFN package and are sampling now. They will be in volume production by the end of April 2011, with suggested resale pricing of $4.50 for the four-port TUSB7340 and $3.50 for the two-port TUSB7320, in quantities of 1,000.
