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 time-domain 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.
