USB Type-C is a USB interface shape standard. It has a smaller volume than Type-A and Type-B. It can be applied to the interface of both PC (master device) and external devices (slave devices, such as mobile phones). type. USB Type-C has 4 pairs of TX/RX split lines, 2 pairs of USBD+/D-, a pair of SBU, 2 CCs, and 4 VBUS and 4 ground wires.
To understand the principle of Type-C, you must first understand its PN definition. The Type-C port has 4 pairs of TX/RX split lines, 2 pairs of USBD+/D-, a pair of SBUs, 2 CCs, and 4 more VBUS and 4 ground wires.
Of course, if the receiving end only needs the DP signal and does not need the USB 3.1 signal, then the DP can use all 4 pairs of TX/RX differential lines for output, so as to achieve up to 4lanes of DP output, providing a total output bandwidth of up to 32.4Gbps (each The lane can output 8.1Gbps), easily realize 5Kx3K60 frame video, even up to 8K×4K 60 frame video (4:2:0 data), this mode is DPonly mode. In addition, in order to be compatible with USB2.0, Type-C also retains USBD+/D- signals for USB 2.0 devices, so just use Type-C interface, USB2.0 and even USB 1.0 devices can also support front and back insertion. It is worth mentioning that the DP+USB2.0 mode can be realized by using USBD+/D- in conjunction with the above DP only mode. DP occupies 4 pairs of TX/RX differential lines, USB only uses D+/D-. Under normal circumstances, the USB2.0 differential signal will only be connected to one side, because the USB Type-C Plug does not have B6 and B7. USB3.1 only uses 2 pairs of TX/RX differential lines as data lines. Connect TX1/RX1 when plugging forward, and connect TX2/RX2 when plugging backwards. It can be seen that in any case, there will be 2 pairs of differential lines that are not used. Yes, the DP alternate mode is to load the DP signal on the two pairs of “excess” differential lines, so as to realize the simultaneous operation of USB 3.1+DP.
In theory, the USB-C port has a maximum transfer rate of 10GB per second. But Apple says the new MacBook’s USB-C port has a maximum transfer rate of 5Gbps. The maximum output Voltage is 20 volts, which can speed up the charging time. And USB-A, so far the limit transfer rate is 5Gbps, the output voltage is 5V.
USB-C can be compatible with the old USB standard, but users need to buy an additional adapter to complete the compatibility. Apple said that not only does Apple officially sell adapters, but third-party companies can also authorize production.
Before the advent of Apple’s lightning interface, we may have never thought that the input/output (I/O) interface can be plugged in either front or back. With the arrival of the Type-C connector, all this will change, even if the popularity speed is destined to be Very slowly, but at least this day is not so far away.
Earlier on October 16, Apple said that the European Union’s decision to force the use of the USB-C interface will stifle innovation. The EU denied Apple’s claims, saying the approach was better for consumers and the environment, according to the EU news website.
Anna Cavazzini, President of the EU Consumer Protection Commission, said: “The EU has been pushing for a standard for 10 years that we will no longer need to use a lot of cables, we will only need one. But not all companies agree, and this is the Commission finally universal for chargers The reason why the standard proposes legislation.” In addition, Anna Cavazzini also pointed out: “If a new standard that is better than USB-C emerges, we can adjust the rules.”
Anna Cavazzini said the rule could come into force as early as 2024. Anna Cavazzini said the rule could come into force as early as 2024. It is understood that in September, the European Commission proposed to use the USB-C interface as a universal charging interface for smartphones, tablets, cameras, headphones, speakers, and video game consoles. Apple said the move would be an inconvenience to iPhone users and that it would stifle innovation.
At 1:00 a.m. on September 15, 2021, Apple held a 2021 fall new product launch conference and released the iPhone 13 series of mobile phones, including the iPhone 13 mini, iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max four models, fast charging Compared with previous models, the performance has been improved to a certain extent, and the PD fast charging charger is not equipped.
The appearance ID of the iPhone 13 series is similar to that of the iPhone 12 series, both of which are flat screen designs with vertical borders, using super-ceramic crystal screen panels, and the top bangs are reduced by 20%, supporting IP68 protection level. In terms of performance, the latest generation A15 bionic processor is adopted, the internal structure is optimized to carry a larger capacity battery, and it supports 15W MagSafa magnetic wireless charging. The battery life performance has been improved to a certain extent. The Pro model supports up to 120Hz adaptive high-speed brush. The maximum capacity of iPhone 13 and iPhone 13 mini is 512, and the maximum capacity of iPhone Pro and iPhone Pro Max is 1TB.
Check the iPhone 13 details page on Apple’s official website, and pull to the bottom of the package. You can see that there is only one mobile phone in the package, and one USB-C to Lightning fast charging data cable. The charger and headphones are not delivered. Let’s take a look at the flagship iPhone 13 Pro series. The package also includes only one mobile phone and one USB-C to Lightning data cable. Headphones and chargers are also not included.
In recent years, domestic Android manufacturers can be described as “crazy output” in terms of electric power. At present, the mainstream charging power is only around 50W, but domestic Android directly soars wired electric power to more than 120W, and wireless charging also reaches 50W. Adding the total wireless power to 200W+ is probably not a problem!
According to the news from the Financial Associated Press, at present, OPPO, Xiaomi, vivo, realme and other mobile phone manufacturers have launched 120W fast charging solutions, and some companies have achieved commercial use, and the fastest battery charging speed can reach 13 minutes!
On the other hand, Apple, the latest generation of iPhone 13 Pro Max supports up to 27W fast charge, which is not a little worse than the Android next door!
In fact, the iPhone can reach a charging power of 27W, which can be said to be “exhausted”. In other words, the power of 27W is basically the limit of Apple’s charging interface!
Why do you say that? Because the iPhone still uses the Lightning interface of the old design!
Apple’s earliest interface was the “30-pin” interface in the iPhone4S era. Later, in order to meet diverse transmission needs and more convenient plugging and unplugging, it was replaced by the Lightning interface that has been used today. The Lightning interface was originally used in the iPod Touch 5. Used on the iPhone 5, it is already an “old antique” design!

It should be noted that some media said that Apple is reluctant to give up the Lightning interface because it does not want to lose a lot of licensing fees.
It is reported that third-party Apple accessories generally need to purchase special chips from Apple and obtain MFi authorization. Once USB-C is used and PD charging standard is adopted, most PD chargers and dual-C port data cables on the market will be used directly. By removing the MFi license, Apple will lose a fortune.
The EU emphasizes that unifying USB-C will enhance environmental protection and save users about 250 million euros a year.
Because the USB-C interface is a new type of interface, there will still be some problems with device compatibility in the future. Before the interface is popularized, users still need to use various conversion devices to convert the interface to be able to use it smoothly. For example, USB-C to USB Adapter converter, USB-C Digital AV Multiport Adapter (HDMI converter), USB-C VGA Multiport Adapter (VGA converter), in terms of power supply, a USB-C power adapter is also required.
