You look down on the Type C interface features Guards, quickly give yourself some science!

The Type C interface that can transmit audio

Among the many Type C expansion applications, audio transmission is a more grounded. Using the CDLA audio standard, the biggest feature is that the audio signal is not the same as the traditional analog signal headphones, in the phone, audio player to do digital to analog signal conversion, but the phone all the digital signal transmission to the headset to ensure that the phone output And the headset input digital signal is the same, the maximum reduction in sound quality loss. Leading the phone to listen to the digital age, which also completely end the 3.5mm audio interface of the road

Type C of 8K video transmission function

If the audio transmission is still relatively normal, then transfer 8K video? In this 1080P has just universal, 2K / 4K or enthusiasts to play the horizon, Type C direct play to the 8K ... ...

The new USB-Type-C is based on the DisplayPort Alt Mode standard for early certification. In the new technology development process, the product is usually ready to send before the compliance test procedure is completed. However, conformance testing is critical to ensure that data is successfully transferred and used for a good experience of early products. And Display Port 1.4 version can be a good support for 8K video transmission and display.



But the support does not mean that can be used, after all, the decoding unit, the conversion components are the cost is not from the current state of the market, Apple is very hope that the first fruit powder to achieve Type C audio and video transmission experience, after all, Did not try on the MacBook? And domestic manufacturers millet today released Air notebook also joined the Type c interface.


Type C power supply up to 100W? YES

4.5w (0.9a / 5v) powered USB3.0 let you excited? LOW! Flat type of Cody Type C people peak power supply, but can reach 100W! However, at present, this is not so happy.

Just look at the data, so Niubi Type C completely means faster charging speed ah! This is not the case. This is the case for Type-C that conforms to the USB 3.1 standard. USB 3.1 supports USB-PD (PowerDelivery) power supply standard, the maximum power supply to 100 watts, charging speed will indeed be greatly improved. Can only for the USB 2.0 standard Type-C interface phone, it does not support the real fast charge, for this point, I am afraid only Oh, and perhaps the future will be the main fast-charging Type C mobile phone launched it

High-speed data transmission You think too much

Type C bandwidth can support lossless audio and 8K video transmission, and then use Type C to transfer data will be as fast as light? The answer is that you want more!

The following are the same as the "

146966541119471972.JPEGType C, whether it is theoretical data transmission or power transmission standards are very Niubi, but now many use Type-C interface, the device does not use USB 3.1 standard, only the appearance of change. Moreover, even if your Type-C is the standard USB 3.1 interface, but now the market and some other equipment on the market or USB2.0 / 3.0 standard for the mainstream, the transmission speed is fast and fast

USB2.0 can become USB3.0? This is not a lie

It is possible to convert a USB 2.0 (or USB 1.1) application such as a flash drive, charger, power adapter, external drive or hard disk drive to a USB Type-C connector with flip function, which, of course, Ability, for the electronic circuit in the professional learning of small partners, or try?

The USB Type-C full-function socket pin is mapped as shown below, which shows the socket pin assignments required to support full-featured Type-C cables (this cable can support USB 2.0 and USB 3.1).


When migrating from a USB 2.0 product to a Type-C product, you will not need a USB 3.1 signal, so keep them in a disconnected state (electrical isolation) on a printed circuit board (PCB). The following figure shows the USB 3.1 contacts as a normally open (NC) contact in a Type-C socket.


The pins in the figure above map have two sets of D + and D- contacts. These two sets of pins do not represent there are two separate USB 2.0 paths. In fact, the USB Type-C cable has only one cable for D +, one for the D- cable. The purpose of these two sets of D + / D- contacts is to support the "flip" feature. The product should connect two D + contacts on the PCB and connect the two D-contacts together. When these contacts on the PCB are connected together, there will inevitably be a residual pile. For this reason, please be careful not to make the length of the residual pile more than 2.5mm. Otherwise, you need to pay attention to the signal integrity issues on the USB 2.0 interface.
