Method for controlling signal transmission synchronization

Abstract

The invention belongs to the field of electronics, and relates to time delay control technology for the synchronization of a plurality of transmission lines of a printed circuit board, in particular to a method for controlling signal transmission synchronization. The prior technical proposal realizes the control for the delay among the transmission lines by adjusting the length of the transmission lines under the condition that the dielectric constant is unchangeable. Under the condition that the length of the transmission lines is unchangeable, the method of the invention for achieving transmission consistency among channels by adjusting the relative dielectric constants can adjust the time delay of picosecond scale. The practical test result shows that the method can realize good synchronization of the signal transmission, improve the synchronization precision compared with the prior method for realizing delay control among the transmission lines by adjusting the length of traces, and achieves time delay adjustment of picosecond scale.

Description

A method for controlling signal transmission synchronization technical field The invention belongs to the field of electronic technology, and relates to a synchronous delay control technology of multiple transmission lines of a printed circuit board in the electronic technology. Background technique With the development of information technology, electronic devices are getting closer and closer to people's lives, and they appear in almost every corner of life. As an important component, a printed circuit board ("PCB") appears in most electronic devices. In addition to fixing various electronic devices, the main function of the PCB is to provide mutual electrical connections for the various electronic devices on it. Those of ordinary skill in the art know that the substrate of the PCB is made of a material that is insulated from heat and is not easy to bend, and the circuit connection of the electronic device is provided through wires on the surface of the PCB. The main ...
