CES: SuperSpeed USB 3.0 speed boosted for consumer apps


At the 2013 Consumer Electronics Show the USB 3.0 Promoter Group  announced development of a SuperSpeed USB (USB 3.0) enhancement that will add a much higher data rate, delivering up to twice the data through-put performance of existing SuperSpeed USB over enhanced, fully backward compatible USB connectors and cables.

This supplement to the USB 3.0 specification is anticipated to be completed by the middle of this year. These updates will enable higher data rates and allow combining of disk, high-definition audio/video and networking traffic on a single cable — all while maintaining compatibility with billions of existing devices.

Key characteristics of the higher-rate SuperSpeed USB solution include:

1) a new 10 Gbps USB data rate,

2) compatibility with existing cables and connectors,

3) improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency

4) compatiblity with existing USB 3.0 software stacks and device class protocols,

5) compatiblity with both existing 5 Gbps and new 10 Gbps USB 3.0 hubs and devices, as well as USB 2.0 products.

“With USB technology continuing to be the data and power delivery path of choice across personal computing and consumer electronics, we are always looking ahead to how to best improve user experience and connectivity performance,” said Brad Saunders, USB 3.0 Promoter Group Chairman. Doubling SuperSpeed USB performance will be especially beneficial for emerging USB docking and storage applications.”

The 10 Gbps SuperSpeed USB update is targeted for industry review during the first quarter of this year. Further information regarding the specification and plans for pre-release industry reviews will be provided via the USB Implementers Forum (USB-IF) website.
