Bi-directional signal adjusting chip of USB Type-C cable and USB Type-C cable

Abstract

The invention provides a bi-directional signal adjusting chip of a USB Type-C cable and the USB Type-C cable. The chip comprises a memory, a processor and an adapter driver, and the adapter driver isused for conducting regenerative transmission on a high-speed signal; the memory is used for storing procedure codes, the processor is used for calling the procedure codes, when the procedure codes are executed, and the processor is used for executing the following operations that the data transmission direction of the USB Type-C cable and types supported by the transmission data are judged; the on-off states of all bumpers in the adapter driver are configured according to the data transmission direction and the supported types; the data output direction of the adapter driver is kept to be consistent with the data transmission direction, wherein two buffers having the two opposite directions are configured on each data transmission line in the bi-directional signal adjusting chip. The USBType-C cable can achieve bi-directional transmission.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a bidirectional signal adjustment chip for a USB Type-C cable and a USB Type-C cable. Background technique [0002] Virtual reality technology VR refers to the use of computer systems and sensor technology to generate a three-dimensional environment, creating a new way of human-computer interaction, and mobilizing the user's senses of vision, hearing, touch, and smell to enjoy a more realistic and immersive experience. experience. Augmented reality technology AR is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to put the virtual world on the screen and interact with the real world. [0003] The development of VR and AR technology promotes the improvement of video transmission rate and display quality. At present, the video signal transmission between...

Problems solved by technology

Generally, the signal transmission direction of the Re-driver is unidirectional, so the active EMCA where the Re-driver is placed usually needs to identify the data transmission direction of the cable, and the cable must be connected in strict accordance with the data transmission direction, which is not only for the use of VR Inconvenience for users of / AR, and additional steps to wire manufacturing to mark the wire

[0006] In summary, how to solve the problem that when using active EMCA to connect VR / AR devices, the connection must be strictly in accordance with the signal transmission direction of the Re-driver, which has become one of the technical problems to be solved urgently by those skilled in the art
