Dock Introduction to basic concepts

Dock, Also called docking station , The popularity of this kind of products is due to the USB Or the number of interfaces such as video is limited , Users want to expand more or more types of interfaces , To meet the needs of multiple applications . Due to the limitation of notebook interface output power , The docking station usually needs to be powered by its own power adapter .

USB Type-C The emergence of interfaces further extends Dock Application scenarios and functionality . What this article refers to Dock yes ： Docking station with power regulation capability , It is different from rechargeable converter products that do not have voltage regulation capability on the market （ Such as ： Apple launched 1 turn 3 converter ）.

                                                                chart 1 For tradition Dock product

chart 1 For tradition Dock Product schematic , such Dock Its size and weight decide that it is not easy to carry , Manufacturers of various brands in the market Dock It's usually not universal ,USB Type-C The emergence of gives Dock Diverse design elements , The specific performance is as follows ：（ The schematic diagram of the product is shown in the figure 2 Shown ）

                                                                chart 2  USB Type-C Dock Product examples

1. The interface is simple , Only one uplink interface is needed USB Type-C mouth , There is no need to make complex cable connection with the bus of the notebook ;

2. One mouthful can be used in many ways , It can charge the notebook while transmitting data , And play the video in the notebook ;

3. Wide compatibility ,USB Type-C Dock All comply with standards USB PD agreement , Different brands USB Type-C Computer and USB Type-C Dock Theoretically, they can be compatible ;

4. Suitable for all kinds of USB Type-C host ,USBType-C Dock Not only with laptop , It can also be used on tablets and mobile phones ;

5. Ultra small size , Can be carried with you .

USB Type-C Gradually unify the external interfaces of notebook and mobile terminal devices , Driven by the trend , be based on USB Type-C Interface Dock The design will be welcomed by the majority of users , Especially today when the performance of mobile phones and tablets is more and more powerful .

portable Dock Users can use their mobile phones anytime, anywhere 、 Tablet turned into a complete computer , This article is based on Taiwan AG9311 Design belt USB3.0 PD Various cards   RJ45 so as well as 3.5MM Audio output controller Dock The design method provides a design idea and concept with reference value for the majority of peripheral manufacturers .

USB Type-C Type of interface , from USB-IF Organize to make , As early as 2014 I got it in, including apple , Google , Recognized by Intel and other manufacturers , One after another in the 2015 Launch related products in . Compared with all kinds of USB Traditional interface ,USB Type-C Small size 、 High integration 、 Excellent features for easy use . That is to say USB Type-C Interface set data transmission , Power supply , And video . chart 1 Briefly describes USB Type-C Part of the characteristics of .
