Synopsys recently declared that its DesignWare SuperSpeed USB 3.0 xHCI IP has received the USB Implementers Forum (USB-IF) SuperSpeed USB certification. The xHCI regulation offers a technique for the product host controllers to interact with the USB 3.0 software.
The requirements for certification includes that the IP needs to support the U1 and U2 power modes and the four USB transfer speeds, including SuperSpeed (5.0 Gbps), Hi-Speed (480 Mbps), Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps).
The USB 3.0 software has an integrated design that helps designers reduce risks by removing the need for two different USB 2.0 and 3.0 data routes in the company’s system-on-chip (SoC) layouts. The USB 3.0 host controller is designed for a small area and low power applications and is already being used in products manufactured in large volumes. It is suitable for battery-operated, portable systems.
COO and USB-IF president Jeff Ravencraft, stated that achieving USB certification is a critical product highlight showing that the Synopsis DesignWare IP meets up to the essential standards and is the basis for bulk adoption of the USB. The appropriate usage of the U1 and U2 energy saving modes will help enhance the battery life in the upcoming USB products.
