[SI-LIST] Jitter from Crosstalk


I've got a question on crosstalk to pose to the
aggregate wisdom of si-list.

In the problem's most simplistic form assume we have
two transmission lines (an aggressor and a victim).
The two lines are somewhat coupled.

Further assume that the aggressor line has a very
randomized signal on it (say a PRBS 2^31-1 pattern).

Also assume that the signal on the victim line is
completely non-synchronous with the aggressor signal.


Now for the question:

Is the jitter induced on the victim signal random in
nature if the aggressor signal approximates a gaussian
distribution in randomness ?

Since the signals are non-synchronous, they will be "sliding"
by each other in time and therefore the contribution to the
victim signal jitter will be random in time. This will cause
a somewhat 'periodic' contribution to the induced jitter. Is
this a deterministic component ?

So I guess the real question is, given the above assumptions,
is the induced jitter Rj, Dj, or a combination of both.


I'd be interested in hearing any opinions and/or references
to studies on the topic.
