Edge-edgejitter(cycletocyclejitter):两个连续时钟边沿的时钟信号变化高速系统设计中,更关注cycletocyclejitter变化,因为连续的时钟...、时钟jitter——时钟频率上的不确定性1.jitter:是由于晶振、PLL、电源、温度变化等都会造成时钟频率的变化,和布线没有关系。设计中无法避免,只能在设计中留有 数字电路时钟问题——...
当周期抖动的概念扩展到N个周期,就是N周期抖动(N-Period Jitter)。这里N并不特指具体数字,可根据需要得到特定的正整数。比如N分频器,如果分频器是理想的,其实关注的是分频前N个周期的抖动。 相邻周期间抖动(Cycle-to-Cycle Jitter),定义为相邻周期的周期差值。可通过周期抖动...
1)period jitter周期抖动 1.The main contents are illustrated as follows:(1) The definition and categories of jitter are introduced, and three sorts of familiar jitter in serial communication systems named as timing jitter, period jitter and cycle-to-cycle jitter are the emphasis.主要的工作如下:(...
TFP410 芯片里面的关于输入时钟的抖动参数 2ns,具体指的是 TIE,period Jitter、cycle to cycle jitter 的哪一种? t(ijit) IDCK clock jitter tolerance 2 ns Kailyn Chen: 这里应该指的是pk to pk的周期抖动。
This document introduces a general formula to translate the phase noise of a clock source, rated via the Single Sideband to Carrier Ratio (SSCR), to the cycle-to-cycle jitter of the oscillation period. The link allows to seamlessly aggregate the external clock source phase noise, usually ...
也就是Cycle to Cycle jitter = T2 -T1 也就是说,在数学上,Cycle to Cycle jitter 是Period jitter的差分 一般高速示波器测量时钟的时候都会统计3种时钟的总抖动。这三种抖动都是描述时钟的总抖动,有点像位移、速度、加速度的关系(都是描述物体的运动),应用的场合不太一样。下面举例说明一下。
1.To improve the efficiency, traditional half cycle modulation hysteresis control is adopted.本文首先分析了电流半周期调制方式下双Buck逆变器的四象限运行方式及半周期调制原理,提出采用单电流互感器采样的恒频斜坡交截控制。 2.By adopting half cycle modulation,the switching losses and conduction losses of th...
The generator SPC produces pulses SP with uniform distribution of interpulse intervals in such a way that during each full cycle of operation, each interval value occurs exactly once. However, on separate cycles, the interval values may appear in different order due to a suitable permutation imple...
