Nowadays, more and more mobile phones, notebooks, tablets and other devices choose to be equipped with the Type-Ch interface. Why is this interface favored by the market? What are its benefits? Today's Speed Shark Class will talk to you about Type-C interface. What is the
Type-C interface?
Regarding the concept of Type-C interface, the Baidu Encyclopedia explains it as follows: Type-C is the latest USB interface appearance standard, and its size is much smaller than Tpe-A and Type-B. There is no difference between the front and reverse directions of the interface
, and it can be plugged and unplugged at will.
In addition, Type-C is an interface type that can be applied to both PC (master device) and external devices (slave device, such as mobile phones), which is epoch-making.
From the appearance of the interface, the biggest feature of Type-C is that it does not distinguish between positive and negative.
Players who are familiar with DIY hardware know that whether it is the CPU, memory stick, graphics card, or hard disk interface, they all have the "unstop" shape design to prevent the interface from being unable to boot if it is plugged in reverse.
The USB-A type interface that we use most often in daily life also has a dumb-proof design, but due to the small size of the interface, miracles often occur, and the USB Type-C interface solves this problem from the source.
Because of the 24 pins of this interface, the contact function is distributed symmetrically in the center. This enables the device to successfully identify and implement complete functions when forward and reverse plugging. What are the advantages of
Type-C? In addition to being more convenient when plugging and unplugging, the
USB Type-C interface is more importantly, it has extremely strong compatibility.
Data transmission bandwidth up to 10Gb/s
The most common purpose of connecting different devices is naturally data exchange.
The latest USB transmission protocol standard is USB 3.1 Gen2, and its theoretical bandwidth can reach a transmission rate of up to 10Gb/s.
USB Type-C interface is the latest USB interface form factor standard, and naturally supports the USB 3.1 Gen2 standard, which can reach a read and write speed of 1GB per second when transferring files.
In addition to data transmission, this interface also has the ability to transmit power.
USB Type-C interface has USB PD (USB Power Delivery power transmission protocol), which supports up to 20V/5A power output, that is, 100W charging power. In addition to supporting the PD fast charging protocol, the interface of
also supports the DP Altmode video output protocol.
This is achieved by adding an additional Display Port video bus to the original USB bus in the Type-C interface.
means that the video output function of the Type-C interface is USB+DP. Whether it supports DP1.2 or 1.4, , its bandwidth supports high-standard video playback at 4K@60Hz.
When the laptop is connected to an external display device, you do not need to use a power cord to power the laptop when connecting using the Type-C interface. The keyboard and mouse can also control the laptop through the USB-A interface on the monitor, which is the extended function of USB HUB.
This not only solves the problem of messy desktop cables, but also makes it more convenient when transferring equipment. When you get off work or have a meeting, you can walk by unplugging a Type-C cable, which greatly improves efficiency. This is a function that cannot be achieved by the traditional HDMI and DP interfaces.
Don’t forget, the phone also has a Type-C interface. When you have a meeting to discuss plans, do you still have to hold a laptop? You only need a monitor that supports Type-C interface and a mobile phone can complete meeting communication. One wire = N wires, enjoy lightweight office work. Simple, convenient and worry-free.
Therefore, in addition to being convenient for plugging and unplugging, the USB Type-C interface is also extremely compatible with the device. It not only can achieve high-standard data transmission and power supply, but also has the highest specifications of video signal transmission specifications.
In the Type-C era, using a monitor with USB-C port expansion can effectively reduce the number of cables, which is a blessing for most people.
