Phase Noise and Jitter 1 Phase Noise as a Lorentzian SpectrumPoore, Rick
Peace-Mark 谈谈各种晶振的相位噪声(Noise)和抖动(jitter) 晶振是个大家族,除了简单封装时钟振荡器(SPXO) 外,更有压控晶体振荡器(VCXO)、温补晶体振荡器(TCXO)、恒温晶体振荡器(OCXO),以及数字补偿晶体振荡器(MCXO或DTCXO),每种类型都有… 硬之城Allchips打开...
Phase noise display shows the phase noise variation/jitter in the frequency range. Supports up to 20 markers and RMS phase jitter determination. Measurements with Track and Histogram: Up to 12 measurement parameters can be displayed simultaneously as a track function and/or as a histogram. ...
Phase noise is the frequency domain representation of clock noise. Phase jitter, on the other hand, is the time domain instability of the clock signal and is typically expressed in picoseconds (ps). Jitter can be described as the random variation in the actual clock signal's edges versus its...
Phase Noise and Timing Jitter ? 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 ...
晶振的相噪与抖动Phase Noise and Jitter解释如下: 一个晶振在某一偏移频率处的相位噪声定义为在该频率处1 Hz带宽内的信号功率与信号总功率比值。 定义相位噪声是从能量角度来说的,指单位带宽内的功率与总信号功率的比,单位是dBc/Hz,所谓的单位带宽,是指偏离理想频点的单位带宽。 相位噪声是从频域的角度来评估这个...
The RMS jitter can be split up into the random jitter and the discrete jitter. In the frequency domain these two parts can be separated from each other. Where the random jitter refers to the noise floor of the phase noise measurement and the discrete jitter to spurs in the spectrum. The ...
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...
