Figure 23. Self-referred jitter (single and long term)
Figure 24. Cycle-to-cycle jitter
difference between N+1 consecutive clock rising edges and T
difference between N+1 consecutive clock rising edges.
N should be kept sufficiently large to have a long term jitter (ex: thousands).
For N=1, this becomes the single period jitter.
See
Cycle-to-cycle jitter (N period jitter)
This corresponds to the time variation between adjacent cycles over a random sample
of adjacent clock cycles pairs. Jitter(cycle-to-cycle) = Max(Tcycle n- Tcycle n-1) for n=1
to N.
