Abstract

The invention provides a low-voltage differential signal transmission device and a setting method thereof, belongs to the technical field of semiconductors, and solves the problem of influence on signal transmission after passing through a corner during low-voltage differential signal transmission in the prior art. According to the method, an access end, a compensation module and an output end areincluded, one end of the compensation module is connected with the access end, and the other end of the compensation module is connected with the output end, wherein the access end is also connectedwith a corner part in the low-voltage differential signal line, so that the conduction of the low-voltage differential signal line and the compensation module is realized; and the compensation moduleis used for enabling the impedance and the signal transmission time between the inner side line and the outer side line of the low-voltage differential signal line to be consistent after the low-voltage differential signal line passes through the corner part.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a low-voltage differential signal transmission device and a method for setting the low-voltage differential signal transmission device. Background technique [0002] In the field of semiconductors, as the number of electronic devices integrated in the circuit board increases, the circuits in the circuit board become more and more complicated. Different signal transmission lines, such as LVDS transmission lines, may be provided based on different needs. Among them, LVDS (Low-Voltage Differential Signaling, LVDS for short) is a differential signal technology with low power consumption, low bit error rate, low crosstalk and low radiation. This transmission technology can reach more than 155Mbps. LVDS Data is transmitted through a pair of differential PCB traces or balanced cables. In practical applications, the transmission lines are often set out of corners based on the lay...
