Hi,
I think I depend on the kind of jitter you have
first example
we have a clock with ideal period 100ps
so we have a edge at 0ps, 100ps, ....
assuming I have a jitter (Time interval error, TIE) of +-15ps around this ideal edge.
Than
our period jitter (as you mentiond current period - ideal period) could be +- 30ps
our cycle2cycle jitter (as you mentiond current period - previous period) could be +- 60ps
if I use a accumulated jitter over 10 periods I still will have the period jitter (+- 30ps)
-> this is because in this system I do not have a jitter accumulation
second example
we have a clock with ideal period 100ps
so we have a edge at 0ps, 100ps, ....
assuming I have a random jitter (Period jitter) of +-30ps around the ideal period
Than
our period jitter (as you mentiond current period - ideal period) could be +- 30ps (as before)
our cycle2cycle jitter (as you mentiond current period - previous period) could be +- 60ps (as before)
if I use a accumulated jitter over 10 periods I can have in worst case 10 times the period jitter (+- 300ps)
So both systems look quite similar with respect to cycle2cyle jitter and period jitter but this does not give an information about the accumulated jitter.
So I would say
Ja >= Jcc > Jp
