usb3.0
usb3.0接口协议 The original Universal Serial Bus (USB) was driven by the need to provide a user-friendly plugand- play way to attach external peripherals to a Personal Computer (PC). USB has gone beyond just being a way to connect peripherals to PCs. Printers use USB to interface directly to cameras. Mobile devices use USB connected keyboards and mice. USB technology commonly finds itself in automobiles, televisions, and set-top boxes. USB, as a protocol, is also being picked up and used in many nontraditional applications such as industrial automation. And USB as a source of power has become the mobile device charging solution endorsed by international communities across the globe. Initially, USB provided two speeds (12 Mbps and 1.5 Mbps) that peripherals could use. As PCs became increasingly powerful and able to process larger amounts of data, users needed to get more and more data into and out of their PCs. This led to the definition of the USB 2.0 specification in 2000 to provide a third transfer rate of 480 Mbps while retaining backward compatibility. By 2006, two things in the environment happened: the transfer rates of HDDs exceeded 100MB/s, far outstripping USB 2.0’s ~32MB/s bandwidth and the amount of digital content users were creating was an ever increasing pace. USB 3.0 was the USB community’s response and provided users with the ability to move data at rates up to 450MB/s while retaining backward compatibility with USB 2.0. Now, with the continued trend for more bandwidth driven by larger and faster storage solutions, higher resolution video, and broader use of USB as an external expansion/docking solution, USB 3.1 extends the performance range of USB up to 1GB/s by doubling the SuperSpeed USB clock rate to 10Gbps and enhancing data encoding efficiency.
