* former designation: USB 3.0 The DP Alt Mode of the USB Type-C™ connector It is advisably to read the product specifications thoroughly. In this way, for example, a display with USB Type-C™ connector and USB PD support that is connected to a power adapter can charge a laptop while signals can simultaneously be transferred from the laptop to the display.īy the way: The designation USB Type-C™ within the name of a device or product does not in every case guarantee that this device is equipped with USB 3.1 Gen 2 or USB PD. Precondition is the USB PD support of the devices on the one hand and of the cable on the other hand. Thanks to USB Type-C™ and USB PD it is also possible to supply power to bigger or high-performance devices like e.g. Via USB it is not only possible to charge Smartphones or Tablet PCs. Thereby a maximum power consumption of 5 A and 20 V (100 watt) is possible. USB 3.1 supports USB Power Delivery 2.0 (shortened: USB PD) that specifies the power supply. Only in this case the data transfer can work at this rate.ģ Power supply & the specification Power Delivery To achieve the highest possible data rate of 10 Gbps, it is important that both of the connected devices, as well as the used cable, do support the protocol USB 3.1 Gen 2. The USB Type-C™ plug can be used for all USB connections, so also for older USB devices and cables. The fastest transfer mode is the protocol SuperSpeed USB 10 Gbps (USB 3.1 Gen 2).

With this protocol data rates of up to 5 Gbps are possible. The data transfer protocol of the earlier predecessor USB 3.0 is now called SuperSpeed USB 3.1 Gen 1. USB Type-C™ plug offers double-sided usability USB Type-C™ plug offers double-sided usability 2 Higher speed

Which cable end has to be connected to the host and which to the device doesn't matter, because both cable connectors are equally functional. Also with a USB Type-C™ to USB Type-C™ cable, there is no difference between 'start' or 'end'. With USB Type-C™ it doesn't matter any longer where 'top' or 'bottom' are, because the plug fits into the port independently of its rotation direction. The USB Type-C™ plug is double-sided usable, so it can be plugged into the jack in both directions - that means a convenient novelty in comparison to older USB connectors. Most important improvements of this specification are 1 the double-sided usability of plug and cable, 2 the doubled data transfer rate and 3 the increased capability for power supply and charging functionality, for details see below.
