USB Type-C™ & USB 3.2 - The new connection standard

The USB Type-C™ form factor

The USB Type-C™ male with its characteristic elliptic shape is already widespread used in the area of mobile devices. The user friendly 24 pin male enables the simultaneously transfer of current, data, video and audio signals in high quality.

Specifications & advantages of USB Type-C™

Supports 20 Gbps data transfer rate

USB Type-A males are constructed in a way to reach maximum 10 Gbps using these, which corresponds to the USB 3.2 Gen 2 (SuperSpeed USB 10 Gbps) specification. The maximum 20 Gbps of the new USB 3.2 Gen 2x2 (SuperSpeed USB 20 Gbps, see table below) need the USB Type-C™ interface.

Protocol diversity

Beside the USB variants 1 to 3.2, also DisplayPort™, PCI Express, Thunderbolt™, HDMI or MHL signals are compatible. Via a USB Type-C™ connection, the transfer of audio and video data is even possible parallel to the USB data and USB charging current. With appropriate converters, also a VGA monitor can be connected.

User-friendliness

The USB Type-C™ male is twisting-safe constructed. It cannot be plugged into the female the wrong way round and it is therefore not necessary to distinguish between "top" and "bottom". Also with the cable USB Type-C™ to USB Type-C™ you do not have to pay attention to "start" or "end": It does not matter which end of the cable is connected to the host, which is connected to the device, since both connection ends are equivalent in their functionality.

Durability

The USB Type-C™ male is much more robust than its predecessor. According to the USB Implementers Forum (USB-IF) the male is designed in a way that it withstands 10,000 mating cycles. That means, in terms of figure, a Smartphone could be charged once a day for 329 months (= plug in / pull out again), for example. Compared to these 10,000, for the USB 3.0 Type-A male a lifespan of up to 5,000 mating cycles is stated.

Slim and resistant design

The USB Type-C™ connector has a slim design similar to the Micro USB connector, but is robust enough to be completely suitable for use with laptops, tablets or other mobile devices. The USB Type-C™ male with its small measurements of only 8.4 x 2.6 mm is ideally suitable for slim smartphones as well as desktop PCs and entertainment electronics devices.

Compatibility

With USB Type-C™ connectors, connections can also be made to different USB devices (= non USB Type-C™ devices) by using adapters or cables. In this way, pre-existing hardware or peripheral devices can still be used.

Universal

Thanks to their functionalities, the USB Type-C™ interface will gain more and more importance. So already today and also in future at an increasing rate, fewer power adapters for connected devices are and will be needed. For example a laptop can be connected to a docking station that supplies the laptop and other devices with power.

Improved EMC

USB Type-C™ can reduce malfunctions of involved devices because the electromagnetic compability has been upgraded.

USB 3.2 Gen 2x2 – What is it?

Not long ago, the specifications USB 3.1 Gen 1 and USB 3.1 Gen 2 were common. Then the USB-IF decided a change of name: USB 3.1 Gen 2 became USB 3.2 Gen 2. The name „USB 3.1“ does not exist anymore. The brand new specification is now USB 3.2 Gen 2x2 with a maximum data transfer rate up to 20 Gbps, so doubled to its predecessor again. The different names can be confusing, so the following table overview can help:

Old name New name Marketing name Data transfer rate
- USB 1.1 Full-Speed 12 Mbps 12 Mbps
- USB 2.0 Hi-Speed 480 Mbps 480 Mbps
USB 3.0 / USB 3.1 Gen 1 USB 3.2 Gen 1 SuperSpeed USB 5 Gbps
USB 3.1 Gen 2 USB 3.2 Gen 2 SuperSpeed USB 10 Gbps 10 Gbps
- USB 3.2 Gen 2x2 SuperSpeed USB 20 Gbps 20 Gbps

USB 3.2 Gen 2x2 and USB Type-C™ result in the fastest duo

Data transfer performance

The predecessor of USB 3.2 Gen 2x2 is USB 3.2 Gen 2 (SuperSpeed USB 10 Gbps). By this predecessor protocol, data rates up to 10 Gbps can be reached. The currently fastest transfer mode is the protocol SuperSpeed USB 20 Gbps (USB 3.2 Gen 2x2). With it, a data rate of up to 20 Gbps can be reached.

The USB Type-C™ male can be used for all USB connections, even for older USB devices and cables. To reach the highest possible data rate of 20 Gbps, please note that both connected devices must support the USB 3.2 Gen 2x2 protocol. But older cables which support „only“ USB 3.2 Gen 2 (SuperSpeed 10 Gbps) can be used also for applications with 20 Gbps.

USB Power Delivery & charging function

Since USB 3.2 Gen 2 (previous name: USB 3.1 Gen 2, see table above), the power supply specification called USB Power Delivery (shortened: USB PD) is supported. Thereby a maximum power consumption of 5 A and 20 V (100 watt) is possible. The power supply works in both directions.

How does it work? Power supply unit and end device negotiate the combination of voltage and current intensity and so the performance, that means they create a profile. The PSU offers the available combinations and the end device chooses an appropriate profile out of these. USB PD detects and takes notice of the charging direction of the devices connected to each other.

The topology of USB PD

Thanks to USB Type-C™ and USB PD, not only smartphones or tablets can be charged, but also larger or powerful devices such as monitors or laptops can be supplied with power. The prerequisite is USB PD support, for the device on the one hand and the cable on the other. For example, a monitor with USB Type-C™ connection and USB PD support which is connected to a power supply can charge a laptop while simultaneously transmitting signals from the laptop to the monitor.

The USB Type-C™ DisplayPort Alternate Mode

In addition to the USB data line, the USB Type-C™ connector of the laptop and other devices has another function. This function is called DisplayPort Alternate Mode (DP Alt Mode). It allows to connect a monitor adapter to the appropriate USB Type-C™ port of a device. In case this port supports the DP Alt Mode, the signal can be transmitted to the monitor via the adapter or cable.

Monitor diversity thanks to DP Alt Mode

If the device supports DP Alt Mode, appropriate USB Type-C™ to DisplayPort™, HDMI, DVI or VGA adapters can be used in order to connect corresponding monitors.

The relationship between USB Type-C™ and Thunderbolt™ 3

Basic idea of the USB Type-C™ interface is to transfer various kinds of data or signals via a single cable. The initially in 2009 by Intel and Apple introduced standard Thunderbolt™ was following the same purpose. Since middle of 2015, Thunderbolt™ 3 has also been using the USB Type-C™ connector, which can be used on both sides. Thunderbolt™ 3 is using the same male and female connector like USB Type-C™ and supports all USB Type-C™ functions. In addition, the Thunderbolt™ 3 controller has a USB 3.2 controller integrated.
