Detail
USB 3.0 is the second revision of USB (Universal Serial Bus). USB 3.0 supports full-duplex, has several contacts more than USB 2.0, and uses the send list section for data distribution. The USB 3.0 tentative power supply standard is 900mA, and theoretically has the potential to support fiber transmission. The "Super Speed" transmission speed of USB 3.0 is 5Gbit/s, and the theoretical data transmission speed is 625MByte/S. The USB 3.0 is designed to be compatible with USB 2.0 and USB 1.1 and features three levels of multi-layer power management to provide different power management solutions for different devices. Intel's xHCI already supports the USB 3.0 interface and is backward compatible with the USB 2.0 interface. USB 3.0 adopts new packet routing technology, and the cable is designed with 8 internal lines. Except VBus and GND as power supply lines, the remaining 3 pairs are data transmission lines, which retain D+ and D- compatible USB 2.0 lines. , added SSRX and SSTX designed for the new version of the line. The USB 3.0 Standard-A interface continues to be the same size as the previous version, with a blue appearance, but with internal contacts that change, and new contacts will be placed side by side with the current four contacts.
