USB TYPE C
USB Type C is a specification for a reversible plug connector for USB Devices and Cabling.
An important benefit of the USB Type C is that it supports USB 3.1, USB 3.0, USB 2.0 and Thunderbolt Technology.
USB Type C ports can support a variety of different protocols using “AlternateModes”, which allows you to output Power, Data and Video Signals and use of adapters that can output HDMI, VGA, DisplayPort or other types of connections from that Single USB port.
This allows for future devices to streamline their design to offer multiple output solutions through one singular output.
What is Power Delivery
Some external devices like for instance a computer Mouse will also need some power from the USB Port to operate. The Default Power that USB 1.0 and 2.0 can deliver is 2.5Watt (5Volt, 0.5A) and USB 3.0 and 3.1 can deliver 4.5Watt (5V, 0.9A).
For the more power hungry external devices different technologies were developed. It is important to distinguish 2 different ones; “USB Power Delivery” and “USB Battery Charging”
USB Power Delivery: “Power Delivery” works equally well with USB2.0 and 3.x. and it allows power draw up to 100 Watt from the source device. This power can be transferred at the same time the data is transmitted through the same cable. The intent is to permit uniformly charging for laptops, tablets, USB-powered disks and similarly higher power consumer electronics. Please note that an Active USB Type C Cable with E-Marker Chip, like the Club3D CAC-1522, is recommended when making use of Power Delivery up to 100 Watt, to ensure a safe connection.
USB “Power Delivery” is defined by different profiles – and it depends on the manufacturer which configuration would be used. 100Watts is delivered in scale as follows
What is USB 3.1
“USB” stands for Universal Serial Bus and “3.1” is the recently released standard which indicates the technology and specifications it is compliant to.
USB Type C is not the same as USB 3.1 – USB Type C is just a connector shape and the underlying technology could just be USB 2.0 , 3.1 or 3.0.
Furthermore there are different USB Type-C 3.1 versions the “Gen1” and “Gen2”.
USB Type-C 3.1 Gen 1 means that the USB technology used is like USB3.0 (5Gbps)
USB Type-C 3.1 Gen 2 means that it the technology used is USB 3.1 (10Gbps)
To be able to send Video signals over USB 3.1 Type-C (Gen2) the source device
(PC/Laptop) will need to have displayport Alternate Mode Support
Although Thunderbolt 3 is also coming out with a USB Type C connector, it is not the same as USB 3.1 Type C Gen2.
USB Battery Charging
USB Battery Charging technology ensures that one can safely charge mobile devices thru the particular USB Port with Battery Charging Feature support.
Previously a USB Portable Device with a battery and charging capability simply took power from a USB port without any control.
With “BC 1.2” introduced end 2010, a Portable Device can get more power and the battery can be charged faster. It is important to verify that a Portable Device complies with the BC 1.2 specifications while communicating with a Charging Downstream Port and identifying a Dedicated Charger, and ensuring that it continues to operate as a functional USB device.
What is USB Graphic?
USB Graphic Technology allows you to connect almost any kind of display via a standard USB connector or cable. The technology is designed to be simple and easy to use: just install the software, plug in your device and within a few seconds you have got a new monitor, docking station or projector connected to your PC. There is simply no easier way to add a display to your PC or Mac.
