标准摘要
[中文适用范围]: 目的 该测试程序的目的是测量单个数字设备的抖动传输特性,即输出抖动与所施加的输入抖动之比,作为频率的函数。 2 规范 抖动传输要求以抖动模板的形式规定,涵盖指定的增益/频率区域。这些要求旨在确保时钟恢复电路和去同步器相位平滑电路充分衰减抖动。如果数字设备输入和输出端口上出现的抖动之间的关系可以用线性过程(加性和同质)来描述,那么窄带测量将表征其抖动传递性能,术语“抖动传递函数” “ 用来。 [外文原描述]: Enables the measure of the jitter transfer characteristic of an individual digital equipment as the ratio of the output jitter to the applied input jitter as a function of frequency. Jitter transfer requirements are specified in terms of jitter templates, which cover a specified gain/frequency region.
