USB 3.0 Host Controller IP, as used in industry standard Compliance Program

May 28, 2014 // By Graham Prophet
Cadence Design Systems has added production-proven host controller intellectual property (IP) for USB 3.0 to its catalogue. The Cadence USB 3.0 xHCI host controller IP was originally developed by Fresco Logic, a fabless semiconductor company that develops and markets advanced connectivity solutions.

This design IP is used as part of a recommended Peripheral Development Kit (PDK) for compliance testing by the USB Implementers Forum (USB-IF) and has been deployed in over a billion USB ports. Being part of the compliance test ensures interoperability with the large number of USB peripheral controllers available in the market.

Now licensed by Cadence, the USB 3.0 xHCI host controller is being offered as fully supported semiconductor IP as part of Cadence's complete USB IP and VIP solution. Cadence also has an agreement with Fresco Logic to license the next generation of this host controller IP supporting the USB 3.1 protocol.

"This USB 3.0 host controller IP... has been a part of SuperSpeed compliance testing from the start and utilised as a discrete IC in many production systems," said Robert McVay, CTO of Fresco Logic. "With Cadence licensing and supporting it as part of their full USB portfolio, their customers have the immediate benefit of a proven high-performance, low-risk, and lower cost solution for USB 3.0 host applications."

"The addition of the USB 3.0 and USB 3.1 xHCI host controller IP completes the Cadence USB portfolio, complementing our premium USB PHY design in the most advanced process nodes," said Martin Lund, senior vice president, IP Group, of Cadence.

The Cadence USB 3.0 IP is fully configurable, allowing users to achieve the optimised functionality they require, whether it is for mobile or infrastructure applications.
