cycle-to-cycle jitter

Cycle-to-cycle jitter is a measure of the deviation between two consecutive clock periods and is therefore calculated as the time difference between random periods of adjacent cycles.

For many TDC products on the market, this inaccuracy is a major cause of measurement errors. However, with cronologic products, the cycle-to-cycle jitter is significantly lower than the bin size.

Caution should always be exercised when comparing jitter specifications, as different characteristics of the clock cycle distribution may be specified. For some suppliers, the jitter even exceeds the time resolution of the TDC. Common specifications are the 1-sigma interval or the 95% interval of the distribution.
