Phase Noise

Phase Power Spectral Density -- more commonly called “Phase Noise” in Timing applications – is explained in this video and compared to FM radio modulation. Phase Noise refers to the undesired frequency/phase deviations of a clock signal from its ideal frequency, and it is a critically important parameter in data communications; if Phase Noise is too high, it can cause data errors.
