WebAN-815 UNDERSTANDING JITTER UNITS Table 1: BER and RMS Multiplier N For example RJ RMS = 4ps, and the system BER requirement is 1 x 10-12, the corresponding peak-to-peak jitter (rounded up) is: RJpk-pk = 4 x 14.069 = 56.4ps This figure gives us an idea of the allowable jitter budget. Roughly speaking, if the various random jitter … WebFigure 4. Cycle to cycle jitter histogram 2.3 Long-Term Jitter Long-term jitter measures the change in a clock’s output from the ideal position, over several consecutive cycles. The actual number of cycles used in the measurement is application dependent. Long-term jitter is different from period jitter and cycle-to-cycle jitter because it
