| 摘 要： | 针对高速串行信号中存在的抖动问题,对现有的眼图抖动分析方法进行了改进.基于双狄拉克(Dual-Dirac)模型,提出了一种针对眼图直方图的抖动分析方法.该方法可在眼图基准点所在区域确定合理范围做直方图,通过对直方图的分析,成功分离确定性抖动及随机性抖动.通过实验验证了该方法的可行性.

| Abstract: | In view of the jitter existing in the high-speed serial signal,we improve the existing eye diagram analysis method.A jitter analysis method by eye diagram histogram is proposed based on the Dual-Dirac Model.The proposed method can determine the reasonable scope of crossing point in eye diagram to generate the histogram and separate the deterministic jitter from the random jitter by analyzing the histogram.The feasibility of the method is verified through experiments. |
