PhaseNoise to RMS jitter: 具体的相互转换原理此处不做说明,可以参考: Clock (CLK) Jitter and Phase Noise Conversion - Application Note - Maxim (analog.com) 如上图,从PhaseNoise转换为RMS jitter只需要将phase noise每个区间求积分再转换计算就行,这里关键就是如何求积分。 这里定义每个偏移频率为f,每个偏移...
2.2.4 jitter & phase noise 的联系 时域的jitter可由deterministic sideband或者 random phase noise 产生。在Section 2.2可知,确知jitter的弧度峰峰值等于4倍的输出边带的归一化幅度值。本小结,我们将给 random jitter和phase noise spectrum两者建立联系。随机性则决定了我们不能明确计算 jitter 的峰峰值,二是设法求...
5、抖动频域表示 我们比较详细的介绍了功率谱密度的概念,抖动在频域主要是用相位噪声(Phase Noise)来表示,也就是相位功率谱密度的单边带信息(频率大于0的部分)。 系统级我们常用时域的抖动描述。但对于电路级会更广泛的使用频域表示。对于像周期性信号,比如时钟电路。使用相位噪声...
Jitter can be due to deterministic and random phenomena, also referred to as systematic and non-systematic respectively. It is worth mentioning that the benefit of jitter is limited to applications using random number generation. There is hardly any other benefit from jitter. Phase noise and ...

Phase noise and timing jitter – Phase noise ? Measure of spectral density of clock frequency ? Units: dBc/Hz (decibels below the carrier per Hz) ? ? Analog people care about this – Timing Jitter ? Measurement of variations in clock transition edges with respect to reference ? Units: ...
My thought is to determine the jitter floor of the VCXO from the phase noise plot to determine if the oscillator can meet the design requirements and how much I can allow to be transferred from the PLL's reference (Hsync) within the loop bandwidth, for internal error budget, etc. There ...
In this context, accumulated jiiter (long-term jitter) is a measure of the total phase noise in the system. When a signal is multiplied by a clock to up-convert or down-convert, the resulting spectrum becomes the multiplication of the spectrum of the si...
图3给出了RMS Jitter为231fs ,与Si5368 Spec中给出的一致,说明了JitterLab的准确性。图3 Phase-noiseContribution to Random Phase Jitter曲线表示12kHz~20MHz范围内各频率下的噪声贡献。 Fig3. 12k~20MHz 内JitterLab积分结果 2.Excel积分 用Excel计算Si536812k~20MHz的RMSJitter之前应先用10 ^相位噪声^ ^/...
A companion analysis of clock jitter and phase noise of single-ended and differential ring oscillators is presented. The impulse sensitivity functions are used to derive expressions for the jitter and phase noise of ring oscillators. The effect of the number of stages, power dissipation, frequency ...
