USB Type-C fast charging technology has become a trend

Nowadays, fast charging has become a standard feature of major flagship mobile phones, directly affecting the end-user experience. For fast charging technology, there are actually many factors in how to achieve faster and more efficient charging. Need to achieve higher power transmission, but also need the adapter to have sufficient power output capacity, the mobile phone's charging circuit must be within a certain heating range, and then transfer heat to the battery, the battery must also support such a high charging current, which includes A lot of links.
In terms of interfaces, middle and high-end smartphones are now gradually moving towards the USB Type-C interface. The combination of USB Type-C and fast charging is also relatively high in the entire industry, which is a big trend.
Type-C connectors
In December 2013, the USB-IF Association of the United States announced the next-generation USB Type-C connector. Then in August 2014, the relevant industry chain began to be ready for mass production. The highlights of the new interface are a slimmer design, faster transmission speeds (up to 20Gbps) and more powerful power transmissions (up to 100W). At the same time, the Type-C double-sided pluggable interface is its biggest feature. It supports the double-sided plug-in of the USB interface, which officially solves the worldwide problem of "USB will never be plugged in." At the same time, the USB data cable used with it must also be thinner and lighter.
Type-C connectors
Compared with USB 3.0's 9-pin, USB-C has been increased to 24 pins, the data transmission pin has doubled, and the CC pin has been newly added for USB Power Delivery charging, and its abbreviation is well known USB PD fast charge. In the fast charging industry, USB PD is gradually becoming a communication protocol standard. The USB PD protocol is also based on the application of the USB Type-C interface. Once the major fast charging camps and terminal manufacturers adopt the USB Type-C interface, they can achieve full compatibility. At the same time, it also brings new opportunities to the development of fast charge protocol standards, and the application prospects of the combination of USB Type-C and fast charge will also be broader.

Talking about the function, classification and working principle of OTG data line

图片
  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mob...

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and...

BNC interface protocol in video output

图片
In the following, you will be presented with a set of questions and answers about the "What protocol is going on in the BNC interface video output" and the  Konnra Electronics  engineers' Q&A record, so that you can easily understand what protocol is going on in the video output of the BNC interface in the interaction. related question. The core of the problem: What protocol is going inside the BNC interface video output? Problem Description: For example, this bnc interface video output device, BNC is the signal of the H.264 protocol, it is necessary to configure the photoelectric conversion equipment between it and the camera, how to configure it? What kind of docking can it be? Answer: The BNC interface input and output is commonly referred to as the Q9 header, which is used to transmit baseband video signals. The single BNC port of the monitoring device transmits the analog composite signal. The video recorder saves the video file of the analog video signal into...
