TI achieves industry’s first SuperSpeed USB four-port extensible host controller with USB-IF certification
Texas Instruments 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.
“The continuing certification of USB products is key to delivering a smooth and effortless experience to consumers worldwide as they purchase and interconnect their new electronic devices using SuperSpeed USB,” said Jeff Ravencraft, President & COO, USB-IF. “We are pleased with the commitment Texas Instruments has made to this standard by delivering such a broad portfolio of SuperSpeed USB products, including their most recent four- and two-port host controllers.”
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
· 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.
