Hi all, I have done some further reading on the subject...I have drawn a few conclusions :--
1. In case of blocks that are driven by an input clock(eg. dividers),ie the output transition in dependent on the input transition, we measure Edge-to-Edge Jitter Jee.
2. In case of blocks in which transitions of the output are important (eg. dividers whose o/p goes to PFD) , we measure Jitter through time-domain(time-strobed) PNOISE Analysis.
3. In case of blocks in which an output transition is dependent on previous OUTPUT transition, we measure Period Jitter.
4. CYCLE-to-CYCLE Jitter is the maximum Jitter possible assuming complete un-correlated behaviour. PERIOD JITTER,on the other hand, includes some effect of correlation of noise,thereby decreasing jitter.
Pls educate me :- Are all of these statements correct ??
regards, Mayank.
