Analysis of Crosstalk in PCB Design

摘要

Crosstalk is an important EMC problem in printed circuit board design. A wildly used theoretical model based on transmission line theory is presented in this paper. On this basis, the origin and some characters of crosstalk and the factors affecting crosstalk are introduced. The simulation software HyperLynx is applied to analyze the factors. From simulated results, some design features that will reduce crosstalk are concluded.
