USB-C stands for USB Type C, which is an extension of the commonly used USB standard. The characteristic of the new interface is small and exquisite, regardless of the positive and negative direction, more humane. Theoretically, the Type C interface can be used on USB 2.0 and 3.0 buses, but currently manufacturers tend to use Type C with the new generation of USB3.1 transmission specifications.
In summary, USB Type-C has the following characteristics:
1. The maximum data transmission speed can reach 10Gbit/s;
2. Type-C interface size is about 8.3mm×2.5mm slim design;
3. Support "positive and negative insertion" function;
4. The standard specification cable equipped with Type-C connector can pass 3A current and can provide a maximum of 100W of power.
The lightning interface was launched with IPONE5 in September 2012, replacing the 30Pin Dock interface and is 80% smaller. There are 8PIN contacts on both sides of the lightning interface, which supports positive and negative insertion. It has 8 pins on each side, and the white part insulates these pins from each other. The outermost metal actually plays a grounding function, so strictly speaking, the Lightning interface uses a 9Pin pin design. There are a little recessed place on both sides of the connector, this is mainly to be able to be tightly stuck in the slot (there is a spring on the left and right sides of the slot). The Lightning interface can also allow the headset to support higher-quality audio, replacing the traditional 3.5 mm headphone jack. The disadvantage is that it is not compatible with the existing 30PIN accessories, so the original charger and base are not applicable. Another disadvantage is that it does not support the audio output of analog signals, which is somewhat similar to the difference between the DVI interface and the HDMI interface. In other words, if accessory manufacturers, such as speaker manufacturers, launch speakers that specifically support iphone 5 or new iPods in the future, they must also use digital signals, or they must integrate a Digital to Analog Converter in the speakers. .
(Apple lightning interface)
Manufacturers that make Apple’s peripherals must be authorized by Apple’s MFI (Made For IOS), and the plugs used by the manufacturer to manufacture the Apple cable must be purchased from Apple. These plugs are certified and have chips. The difference between non-certification will be warned as long as the plug is connected, and it will even be directly converted to flight mode, indicating that non-certified accessories cannot be combined with Apple products, and will affect the normal use of Apple products. If you do not pop up any prompts, realize seamless connection, play songs normally, transfer data normally, and synchronize data, it is a certified product. The certified plug purchased from Apple costs several dollars (not to mention the specifics). Such a high price is one of the reasons why the original Apple cable sells for more than RMB100. The price of Type-c cable is only the price of a plug of Apple, maybe a little more, the price is more close to the people, and more popular.
In fact, the latest USB 3.1 Type-C has a trend to replace Lightning. Compared with lightning, USB type C has much larger bandwidth, stronger power supply capability and comparable multi-protocol compatibility. The interface is smaller and it can also be plugged in at random. If Apple wants, IOS devices can use the new interface to simplify the interface standards of the Apple ecosystem. At present, foreign markets are paying special attention to Type-C, which should be the general trend. The emergence of Type C specifications has naturally greatly facilitated the daily use of digital equipment, and quickly gained recognition from a manufacturer with its unique advantages. PC computers, tablet computers, smart phones, etc. have begun to be equipped with Type C interfaces. Especially after the promotion of series of big-name manufacturers such as Apple and Huawei, Samsung, Type C is currently attracting attention.
