APP. NOTE 4 S TSU FREQUENCY CONTROL, INC. JITTER NOTES CLOCK JITTER Clock jitter is defined as the deviations in a clock's output transitions from their ideal positions. The deviations can either lead or lag the ideal position, measured at a specified voltage level, and hence jitter is often specified
