  • One minute to understand the difference between USB3.1 and Type-C interface
    Sep 25, 2017

    USB3.1 and USB Type-C are two different things.

    Strictly speaking, USB 3.1 is a USB-based latest transmission standard. Compared to the previous generation USB3.0, the new USB 3.1 to improve the bandwidth while also greatly improving the coding rate.

    USB 3.0 is 8b / 10b encoding, each transmission 10bit data, there are 2bit as a check code exists, so the bandwidth loss will be as high as 20% (2/10). While the use of USB 3.1 is 128b / 132b encoding, 132bit data in the use of only 4bit as a check code, so the transmission loss rate is very low, only 3% (4/132).

    The USB Type-C is an interface standard. USB 3.1 interface standard a total of three, namely USB Type A, USB Type B and USB Type-C. The USB Type-C due to various advantages, has become the most promising interface of the interface interface.

    So there is no absolute association between USB 3.1 and USB Type-C. USB Type-C interface does not necessarily support the USB 3.1 standard, the same, the use of the USB 3.1 standard interface is not necessarily USB Type-C interface.
