Crosstalk among Multiple Stripline Traces Crossing a Split

Abstract

In practical printed circuit board (PCB) designs, it is common to split power/ground planes into islands, area fills, or plane portions. Consequently, it may be inevitable to route signal traces crossing a split due to ever-increasing circuit density in design. These traces can experience more crosstalk than in the scenarios with solid reference planes. in this paper, underlying physics is studied to understand the noise coupling mechanisms and the split- related resonances. in addition, parametric studies are conducted to determine the dominant PCB parameters that affect the crosstalk levels. Lastly, an empirical expression is developed and then validated to calculate the crosstalk among traces crossing a split reference plane as a function of geometric parameters for practical engineering applications.
