Or achieving a large unified interface, where is the confidence of Type-C from?
(Last Updated On: February 27, 2019)
Speaking of “Type-C“, I believe that everyone will not be unfamiliar, because the manufacturers who have made a big fuss about it recently have a lot of facts, but it is necessary to specify what Type-C is. It is estimated that many people can only say “can be positive.” Anti-plugging “a kind of USB” and so on. In fact, Type-C’s doorway is not only the case, even if the core of the same Type-C interface product may be different, coupled with various misunderstandings of the network circulation, the word about Type-C can be said to be different, so this time for everyone in detail Interpret Type-C.
Since the Nokia N1 tablet and the Apple 12-inch new MacBook are equipped with USB Type-C interface, in 2015, various manufacturers have launched or will launch mobile phones, tablets, ultrabooks and other products equipped with USB Type-C interface, setting off a wave of interface innovation. , USB Type-C or will achieve a large unified interface, then what is the USB Type-C interface?
The SB specification was first proposed in 1995 by USB-IF (USB Implement Forum) consisting of Intel, IBM, Compaq, Microsoft, NEC, Digital, and North Telecom. USB-IF was officially proposed in January 1996. USB 1.0 specification, the USB 2.0 data transmission speed set in 2000 can reach 480Mbps, and the subsequent USB 3.0 maximum transmission is up to 5.0Gbps, introducing full-duplex data transmission, and the maximum data transmission speed to USB 3.1 is 10Gbps.
1, the highest data transmission speed reaches 10Gbps, based on the USB 3.1 specification
2, the new interface design, size about 8.4mm x 2.6mm, slim interface
3, support the front and back sides of the insertion, can withstand 10,000 times of repeated insertion and removal
4, can be used to transmit DisplayPort signals, support 4K UHD image transmission
5, USB Power Delivery, can support charging
6, can provide a maximum of 100W power transmission
7, power output capability: standard cable 3A, interface 5A
8, Better electromagnetic interference (EMI) and radio frequency interference (RFI) mitigation characteristics
9, will be heard after the correct insertion
Type-C has a total of 24 pins, while the USB 3.0 interface is usually 9 to 11, and USB 2.0 has only 4 pins. The increase in stitches did not cause the Type-C interface to become bulky. In fact, it also reduced the size (relative to the standard port) to meet the needs of mobile devices.
Type-C or implementation interface
USB is a universal serial bus interface. We touch the standard USB interface on the PC at most. With the development of electronic consumer products to more forms, the USB interface is updated. In order to meet the needs of different products, the USB interface is divided into Type-A and Type. -B physical interface. These two interfaces are derived from standard, Mirco, and Mini interfaces. Due to different interface configurations, interfaces cannot be used together. To the USB 3.1 specification, the Type-C interface has been introduced. In fact, it is only a physical structure standard. Regardless of USB 3.0 or USB 3.1 or USB 2.0, Type-C interface can be used. It is not only the USB 3.1 specification that has Type-C. interface. Type-C’s new interface design is designed for thin and light mobile devices (such as smart phones, ultrabooks, tablets, etc.), or will achieve a unified interface. Although Type-C can achieve a large unification of interfaces, it is a new physical interface, which is not universal with Type-A and Type-B interfaces on current products.
Type-C interface can be inserted
In daily computer use, the mouse plugging and unplugging will always encounter the situation of plugging in, and the plugging is correct. This also makes many people feel distressed. Type-C can be inserted on both the front and the back, and the interface has no directionality. The user avoids the possibility of inserting errors during use.
Type-C audio, video transmission speed and 100W power supply capability
The Video Electronics Standards Association (VESA) announced that DisplayPort’s video transmission technology supports Type-C in the USB 3.1 specification developed by USB-IF, allowing Type-C to have relay audio and video signals, supporting 4K. Resolution image transmission. In addition to the DP signal, the new Alternate Mode in the USB Power Delivery Specification 2.0 allows non-USB signals to be transmitted over the USB interface, supports the USB Power Delivery 2.0 specification, and can supply up to 100W.
Microsoft Windows 10 introduces support for Type-C. Not only does the desktop version of Windows 10 natively support the USB Type-C interface, but the mobile version of Windows 10 also supports the mobile phone with USB 10 operating system and USB main device or USB accessories. Data exchange and video sharing between the two. For example, the mobile phone interacts with USB peripheral devices, supports XboxOne remote control, mouse, keyboard, socket and external display or TV using USB Type-C interface. Type-C will open a new connection mode.
