摘要
随着电路的互连已进入GHz时代,串扰问题在MHz时代不明显的问题变得越来越明显。基于Hyperlynx软件,分别对近端串扰和远端串扰进行仿真实验,期望找到合理处理串扰问题的解决方案。由实验得到,缩短耦合长度可以使近端串扰成正比减小的结论;在微带线条件下,通过缩短耦合长度或者延长上升时间分别可以使远端串扰成正比和成反比减小的结论。
As the circuit interconnection has entered the era of GHz, crosstalk problems is not obvious in the era of MHz is becoming more and more obvious.Based on Hyperlynx software, respectively to do the experiment of the near-end crosstalk and far-end crosstalk ,expecting to find reasonable processing crosstalk solution of the problem.By experiment, shorten the coupling length can reduce the near-end crosstalkin direct proportion; Under the condition of the microstrip line, shortening the coupling length orincreasing rise time can reduce the far-end crosstalkin direct proportion orin inversely proportion.
