WebFeb 27, 2024 · 2)周期间抖动(cycle-cycle jitter) 测量任意两个相邻时钟或数据的周期宽度的变动有多大,通过对周期抖动应用一阶差分运算,可以得到周期间抖动。 这个指标在分析锁相环性质的时候具有明显的意义。 WebApr 27, 2024 · First, input timing jitter (in this case, duty cycle distortion) is converted into “vertical noise,” which for the given example is a non-zero DC offset. Then, at the output of the channel this DC offset moves a considerably attenuated “signal” up or down and converts it into a much larger timing variation (output jitter). Both ...
Webckgiven by Timing jitter is commonly referred to as time-interval error (TIE) as this is just the error in the transition times of our signal. Further, at least for nearly sinusoidal signals, … WebOct 3, 2007 · Jcc is cycle-to-cycle jitter. It is a metric designed to identify large adjacent cycle displacements. It is like edge-to-edge jitter in that it is a scalar jitter metric that …
Web4.3. Cycle-to-Cycle Jitter. Cycle-to-cycle jitter measures the change between two adjacent clock cycles. This is shown in Figure 3. Figure 3: Cycle-to-Cycle Jitter Definition. Mathematically, cycle-to-cycle jitter can be represented as: j cc = period current cycle - period last cycle (5) Where: j cc is the instantaneous period jitter of a given ...
