TransDimension Achieves ULPI Controller IP Certification at Industry's First Hi-Speed OTG Compliance Workshop; Certification Ensures Lower Risk for Customers Integrating High-Speed USB into System-on-Chip Solutions.

IRVINE, Calif. -- TransDimension, a leading provider of USB USB
 in full Universal Serial Bus

Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer.
 connectivity solutions for embedded applications, today announced the successful completion of the industry's first USB Implementers Forum The USB Implementers Forum, USB-IF, is a non-profit organisation to promote and support the Universal Serial Bus. Its main activities are the promotion and marketing of USB, Wireless USB, USB On-The-Go, and the maintenance of the specifications, as well as a compliance program.  (USB-IF) Hi-speed On-The-Go (OTG (1) See USB OTG.

 USB3300 stand-alone transceiver. The successful completion of the certification testing assures a low-risk implementation and faster time to market for customers that are integrating high-speed USB into their system-on-chip (SoC) solutions.

+ Low Pin Interface (ULPI) block and SMSC's USB3300 ULPI stand-alone physical layer transceiver (PHY), are the first high-speed USB products with the ULPI interface to pass this compliance testing.

According to Pete Todd, vice president of sales at TransDimension: "Being the first ULPI-enabled solution to pass high-speed host and OTG compliance testing by the USB-IF has validated the hard work of our world-class development team. Our solution was the first high-speed USB OTG IP core on the market and now it is the first ULPI solution to achieve the high-speed certification. This unmatched maturity and performance allows our IP core to remain clearly differentiated in a competitive market. With the ULPI interface, ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. , SoC and FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market.  designers can now leverage an off-the-shelf high-speed USB solution to accelerate their product's time to market without compromising on pin count or cost."

The ULPI interface is a modification to the well-known UTMI+ link/PHY interface and significantly reduces the pin count necessary for discrete USB transceiver implementations to support host, device or OTG functionality. This low pin count interface allows transceivers to be kept separate from the associated digital ASICs as the technology nodes become smaller and integrating the PHY becomes more complex and expensive.

Todd added: "Working with SMSC has been mutually beneficial as it has allowed both parties to conduct rigorous interoperability testing between our high-speed OTG IP and SMSC's USB3300 PHY. This translates to production readiness for the benefit of our mutual customers. Achieving compliance with the new high-speed OTG test procedure, in addition to the previously announced high-speed peripheral and full-speed OTG certification, means TransDimension and SMSC have successfully turned the 'triple play' of high-speed USB compliance testing."

TransDimension and SMSC were the first companies to achieve successful completion of the USB-IF OTG compliance testing in December 2004. The companies also achieved the first USB-IF certification of a ULPI controller and transceiver in November 2004. High-speed OTG compliance testing is governed by the USB-IF.
