Spectral Analysis of Time-Domain Phase Jitter Measurements

A simplified overview of time-domain jitter measurements is presented in this paper. The relationship between the timedomain jitter measurements and the power spectrum of the phase jitter is described using fundamental Fourier properties and basic random variables analysis. This leads to a unifying analysis and the results are in agreement with commonly accepted understanding of jitter accumulation in oscillators. The presented analysis also provides the basis for comparing different jitter measurements.
