WELCOME USB3.0 TECHNOLOGY
USB 3.0 enables more demanding applications compared to USB 2.0 by addressing
its limitations:
• Bandwidth - 5.0 Gb/sec SuperSpeed (SS) vs. 480 Mb/sec (High Speed) rate
• Power Conservation - link power states (U0 - U3) and function power management
• Data Flow Control - poll once versus poll multiple times
• Error Handling - End-to-end and port-to-port error detection and retries versus only end-to-end retries with USB 2.0.
The additional bandwidth provided by USB SS transactions can benefit applications like real-time audio and video streaming that require higher bus bandwidth at regular intervals.
A major feature of this
topology is its support of all wired USB speeds (LS, FS, HS & SS), and this is accomplished via the two separate buses that are integrated into USB 3.0 cables, connectors and hubs. WHEREAS The standard USB 2.0 bus consists of a single differential pair that operates
in a half-duplex model.
