Figure A-3 Jitter Definitions
The relative deviation of tnom is at its maximum for one clock period, and decreases towards zero for larger
number of clock periods (N).
Defining the jitter as:
J(N)
=
max

N-t--m---⋅--i-nt--n-(--o-N---m-)-
For N < 100, the following equation is a good fit for the maximum jitter:
