Abstract:

Serpentine guard trace is regarded as an alternative solution to traditional guard trace in highspeed circuit, but process of proposing serpentine guard trace dont consider how to make the ability of crosstalk suppression better. According to the principle that serpentine guard trace basic characteristic affects coupling parameters, this paper analyses termination strategies and farend noise variation with characteristic variation via full wave solver simulation, and concludes reasonable serpentine guard trace design method. The result shows that shorting is the best termination strategy, and when signal edge changes quickly, the serpentine that are width, height and short should be used as guard trace.

Key words: guard trace;serpentine;far end crosstalk
