后处理阶段噪声 AN279:Estimating Period Jitter from Phase Noise(https://www.silabs.com/documents/public/application-notes/AN279.pdf),描述了如何根据对相位噪声积分应用4[sin(pi* f * tau)] ^ 2权重因子,从相位噪声中估计周期抖动。加权因子主要是+20dB / dec高通滤波器,直到在半载波频率达到峰值。 事实...
和抖动相关的名词非常多：时钟抖动，数据抖动;周期抖动，TIE抖动，相位抖动，cycle-cycle抖动;峰峰值抖动(pk-pk jitter)，有效值抖动(rms jitter)；总体抖动(Tj)，随机抖动(Rj)，固有抖动(Dj);周期性抖动，DCD抖动，ISI抖动，数据相关性抖动；定时抖动，基于误码率的抖动;水平线以上的抖动和水平线以下的抖动……...

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,每个偏移频率对应的phase noise为L(f),载波(时钟)频率为fc,那么Jitter_rms则为...
is performed when the x-axis may be logarithmic, as well as taking into account other things which are hard to get correct from the simplistic integration approaches normally taken (for example, K-cycle jitter can't really include noise effects from frequencies much lower than 1/(K*period))...
You're working with a signal containing only random noise, and you know its jitter value in seconds RMS. For this calculator, the applicable type of jitter for data signals is time-interval error (TIE). For clock signals, the applicable type of jitter may be anything (TIE, period jitter,...
PROBLEM TO BE SOLVED: To provide a jitter measuring instrument capable of measuring the effective value of jitters in a short period of time. SOLUTION: The jitter measuring instrument is provided with a means for inputting an RF signal containing disk rotational cycle information, a means for de...
The period jitter used to fit the ADC performance at high IF projects a one-cycle σT = 1.48ps, in very good accordance with the value previously obtained, which validates the method proposed. Fig.8 shows the SNR matching against AIN when the same σT is used, and the thermal noise -...
The RMS of a periodic function is equal to the RMS of one period of the function. The RMS ...
