Super speed usb3.0
- 1. SEMINAR ON SUPER SPEED USB3.0 1
- 2. INTRODUCTION • The USB 3.0 Promoter Group announced on November 17, 2008, version 3.0 and submitted to USB-IF • The first certified USB 3.0 consumer products were announced January 5, 2010 2
- 3. UNIVERSAL SERIAL BUS • Designed to allow many peripherals to be connected using a single standardized interface socket. • Consists of a host, USB ports, and peripheral devices connected in a tiered-star topology • Also called as Superspeed • Provides power to low power consuming devices 3
- 4. Pre-releases 1 USB-IF formed 1 USB 1.0 specification 12 Mbit/s 1 USB 2.0 specification 480 Mbit/s 1 USB 3.0 specification 5 Gbit/s 2010 USB 3.0 devices in market 4
- 5. Architectural components Hub Provides electrical interface between devices and host. Functionalities Types Host Types Functionalities 5
- 6. DUAL BUS ARCHITECTURE • USB 3.0 is a physical SuperSpeed bus combined in parallel with a physical USB 2.0 bus 6
- 7. SUPER SPEED CONNECTION Device notifies it is connected Host makes request Device ready notifies this with ERDY Else tells host unavailable to process by sending NRDY 7
- 9. CABLE STRUCTURE • One power pair • One twisted signal pair for USB 2.0 data path • Two twisted signal pairs for the SuperSpeed data path. • Supports full duplex mode 9
- 10. CONNECTOR PINS 10
- 11. FEATURES • Transfer Rate • Backward compatibility • Power specifications • Cable length • Transfer mode 11
- 12. USB 3.0 vs USB2.0 USB 3.0 USB 2.0 •Super speed High speed •900 mA power 500 mA •Full duplex Half duplex 12
- 13. ADVANTAGES • Super speed • Power efficiency • Efficient when compared to its competitors • Backward compatibility DRAWBACKS • Cable length is limited to 3m. • Intel at present not supporting 13
- 14. CONCLUSION • USB 3.0 wil also be popular like earlier versions. • As it is backward compatible it will be used in the new computers and devices • High speed communication protocol. 14

- USB-IF,managing body of usb specification The USB 3.0 Promoter Group announced on November 17, 2008, that version 3.0 of the specification had been completed and was transitioned to the USB Implementers Forum (USB-IF), the managing body of USB specifications. [57] This move effectively opened the specification to hardware developers for implementation in future products. The first certified USB 3.0 consumer products w at the Las Vegas Consumer Electronics Show (CES), including two motherboards by ASUS and Gigabyte Technology. [
