USB 3.0 Description
Designed by a consortium of companies including Intel, USB 3.0 (also known as SuperSpeed USB) is improved and next-generation version of the Universal Serial Bus today, version 2 (USB 2.0). USB 3.0 connectivity to meet today’s demand between computers and peripherals. The main features of a high transfer rate up to 4.8 Gbps, capable of providing high-definition video content or connection to the terabytes of storage devices. To take advantage of high speed, but a new cable must be used between computers and peripherals.
In addition to USB 3.0 high transfer rate is very energy efficient. It includes power management functions, so that the host computer and peripherals to save power when idle. Another prominent feature USB 3.0 is that it is able to provide additional power for power-hungry apparaten op, bijvoorbeeld, 150 mA to a non-configured device tot 900 mA the device is configured.
USB 3.0 is characterized by a new physical connection through additional physical bus which consists of four cables. These cables carrying differential signals (both accepted) to send a higher throughput, in addition to the four cable provided (electricity, land and a pair of differential data) for USB 2.0. However, the design for this new adapter has the same rectangular shape is maintained – as used in USB 2.0 – connector, so USB 3.0 is fully compatible with USB 2.0.USB 3.0 high throughput is achieved with the aid of two-way data interface. To identify, USB 3.0 uses asynchronous method is not the election.
Applications that may be for USB 3.0 is a high-bandwidth devices. This includes external hard drives, high-resolution webcam, video surveillance, multi-channel audio interface and Blu-ray drive.
