SUPER SPEED USB3.0
[attachment=55765]
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
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
How Communication
Endpoint built into device by manufacturer
Endpoint addressable by (device address , endpoint number)as specified in packet sent by host
If data from host to endpoint an OUT packet sent
If data from device to an IN packet sent by host
Power
50% more power provided(100-150mA)for
unconfigured device.
80%more power provided(500-900mA)for
configured device.
Link level power management
Continous device polling eliminated
PHYSICAL LAYER
Physical connection between downstream port and upstream port
If connected reciever termination enabled
No signalling occurs generates LFPS
8 bit data scrambled and encoded to 10 bit,sends to link layer
Link layer to physical
USB 3.0 vs FIREWIRE,ESATA
6 times faster than firewire 800
Faster than esata
esata cannot provide power
USB 3.0 has improved power management, meaning that devices can move into idle, suspend, and sleep states
CONCLUSION
USB 3.0 wil also be popular like earlier versions.
Will replaces firewire etc
As it is backward compatible it will be used in the new computers and devices
