Jitter is the deviation of a timing event of a signal from its ideal position. Jitter is complex and is composed of both random and deterministic jitter components. Random jitter (RJ) is theoretically unbounded and Gaussian in distribution. Deterministic jitter (DJ) is bounded and does not follow any predictable distribution. DJ is also referred to as systematic jitter. A technique to measure period jitter (RMS) one standard deviation (1) and peak-to-peak jitter in time domain is to use a high sampling rate (>8G samples/s) digitizing oscilloscope. Figure shows an example of peak-to-peak jitter and RMS jitter (1) of a QT78AC-24MHz, at 5.0Vdc. Phase Noise and Phase Jitter Integration RMS jitter (1): 5.37ps Peak-to-peak jitter: 43ps Phase noise is measured in the frequency domain, and is expressed as a ratio of signal power to noise power measured in a 1Hz bandwidth at an offset frequency from the carrier, e.g. 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, etc. Phase noise measurement is made with an Agilent E5052A Signal Source Analyzer (SSA) with built-in outstanding low-noise DC power supply source. The DC source is floated from the ground and isolated from external noise to ensure accuracy and repeatability. In order to determine the total noise power over a certain frequency range (bandwidth), the time domain must be analyzed in the frequency domain, and then reconstructed in the time domain into an rms value with the unwanted frequencies excluded. This may be done by converting L(f) back to S(f) over the bandwidth of interest, integrating and performing some calculations. Symbol Definition L(f) Integrated single side band phase noise (dBc) S (f)=(180/)x2 L(f)df Spectral density of phase modulation, also known as RMS phase error (in degrees) RMS jitter = S (f)/(fosc.360) Jitter(in seconds) due to phase noise. Note S (f) in degrees. The value of RMS jitter over the bandwidth of interest, e.g. 10kHz to 20MHz, 10Hz to 20MHz, represents 1 standard deviation of phase jitter contributed by the noise in that defined bandwidth. Figure below shows a typical Phase Noise/Phase jitter of a QT78AC6, 5.0Vdc, 80MHz clock at offset frequencies 10Hz to 5MHz, and phase jitter integrated over the bandwidth of 12kHz to 1MHz.
