Problems solved by technology

However, adding special hardware or software to the active cable to monitor and analyze low-speed sideband signals not only increases the area and power consumption of the active cable signal processing circuit, but may even increase the cost of product design and manufacturing process. Difficulty and production costs
Mistakes in this process, low-speed sideband signals will also cause changes in the original electrical characteristics of the system, thereby affecting signal transmission and system compatibility
[0004] In addition, because the high-speed signal processing chip itself has a bandwidth limitation, it is necessary to design a more complex circuit on the chip if it wants to be compatible with high bandwidth (12Gbps) and low bandwidth (below 100MHz) in the case of limited power consumption and area. , and even if the chip bandwidth is designed to be compatible with high bandwidth and low bandwidth, it is necessary to make specific settings for the chip according to different application scenarios
That is to say, it is necessary to know whether the current application is low resolution or high resolution, and then modify the software or hardware of the active cable, making the program more complicated

Abstract

The invention relates to a device compatible with multiple transmission rates of an active cable and a method thereof. The active cable comprises a front-end circuit and an output circuit, and the device comprises: a rate detection unit connected to an output of the front-end circuit and configured to detect a current rate of an output signal of the front-end circuit and compare the current rate with a rate threshold value to obtain a comparison result and a signal configuration unit that is respectively connected with the rate detection unit and the output circuit and is used for receiving the comparison result from the rate detection unit and according to the comparison result, determining to configure the output circuit with one of a plurality of parameter configurations so as to enable the output circuit to carry out data transmission in a working state adaptive to the current rate. According to the scheme of the invention, the compatibility of the active cable can be improved.

Description

technical field [0001] The present disclosure generally relates to the field of active cable technology. More specifically, the present disclosure relates to an apparatus and method for compatibility with multiple transmission rates of an active cable, an active cable apparatus, and a computer-readable storage medium. Background technique [0002] An active cable usually includes connectors at both ends and a copper wire or an optical cable connecting the two connectors to realize the transmission of data signals (such as video data and audio data) for displaying the data signals. At present, in order to support 4K or even 8K high-resolution display, the current audio-visual transmission protocols have increased the communication bandwidth. For example, the DisplayPort ("DP") 1.4 protocol stipulates that a single channel can support a maximum bandwidth of 8.1Gbps. In the latest High Definition Multimedia Interface ("HDMI") 2.1 protocol, a fixed rate link (Fixed RateLink, "...
