Problems solved by technology

Therefore, when the signal transmission path is affected by the impedance of external components, the speed, strength, and even integrity of signal transmission will be attenuated again. Therefore, external components may become a stumbling block for high-speed serial transmission systems 1 that cannot further break through the speed bottleneck

Abstract

A high-speed serial transmission multi-task transmission module has at least one external signal connection terminal and at least one circuit connection terminal. The multi-task transmission module includes a multiplexer and at least one resistance unit. The multiplexer includes a plurality of switches, and each switch has a first terminal and a second terminal. At least one resistance unit is coupled to the multiplexer, and each at least one resistance unit is coupled to each at least one external signal connection end. The first end of each switch is coupled to at least one external signal connection end, and the second end of each switch is coupled to at least one circuit connection end. The multiplexer is used to switch multiple links for signal transmission. The at least one resistance unit is used for eliminating signal reflection of at least one external signal connection end during signal transmission.

Description

technical field [0001] The invention provides a multi-task transmission module, in particular to a high-speed serial transmission multi-task transmission module and its electronic device. Background technique [0002] Nowadays, with the rapid development of technology, the speed of information transmission plays an important role. In a wired high-speed communication transmission system, if it is necessary to perform signal switching and selection, it is necessary to add a multiplexer to the signal transmission path in the system. [0003] see figure 1 , figure 1 It is a schematic diagram of a traditional high-speed serial transmission system. The high-speed serial transmission system 1 includes a multiplexer 10 , a transmitting circuit block 11 and a receiving circuit block 12 . The multiplexer 10 is coupled to the transmitting circuit block 11 , and the receiving circuit block 12 is coupled to the multiplexer 10 . More specifically, in practical applications, the trans...
