Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2, embodiment 1: the embodiment of the utility model provides an in, a take gain amplification control system's USBTYPE-C cable, including USB3.1 TYPE-C connector, gain amplification control system, USB3.1 cable and EAMRKER chip, USB3.1 TYPE-C connector, gain amplification control system, USB3.1 cable and EAMRKER chip connect gradually.
The gain amplification control system comprises a main control chip U1 and a power supply module. The power supply module adopts an SGM2021-1.8V power supply conversion chip. The signal input end and the signal output end of the main control chip U1 are both connected with a USB interface.
The gain amplification control system plays a main role in amplifying the TYPEC high-speed signal and reducing the influence of the cable on signal attenuation, so that the signal transmission distance is longer, or the difficulty of the production process is reduced.
The gain amplification control system may be located at the input of the signal (note: near HOST device), in the middle of the cable, at the output of the signal (note: near DEVIECE device)
The length range of the gain amplification control system is up to 12 meters (L is less than 12 meters), and the length of the gain amplification control system can be different according to the quality of the cable. Under the same fixed cable length, such as 3 meters in length, the cable is provided with a gain amplification control system, the production process is simple, the USB3.1 GEN 2 standard can be easily achieved, the cable is not provided with the gain amplification control system, the production process is complex, and the USB3.1 GEN 2 standard can not be achieved; under the same process production standard, the length of the cable can be increased by the aid of the gain amplification control system.
The gain amplification control system can be used in a video switching system using USB3.1 TYPE-C CABLE as input, a HUB system, a DOCKING system, such as a USB3.1 TYPE TO HDMI product, TO increase the length of the input line of the product.
In embodiment 2, based on embodiment 1, the main control chip of the gain amplification control system includes NXP PTN3814, TI TDP142, silicon valley digifax RD1011, and the like.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
