Hi guys, Can anyone point me to a paper/book describing the analysis of the discrete time PLL? All I could find are books describing the nonlinear analysis of the continuous time PLL -- an analysis that is based on nonlinear differential equations. A discrete time analysis avoids the difficulty of continuous time white noise, etc. This is all for analysing the mean time between phase slips of a decision directed carrier recovery loop. Thanks, Nimrod.
Discrete time PLL - mean time between slips

Floyd Gardner's PLL book is one of the best, but I'm not positive that it has probability of slip analysis. I think it does, but you might want to confirm first. Blanchard's book is also good, and likely to have cycle slip analysis. Both are primarily continuous-time analyses but the analyses hold (for the most part, at least the techniques hold) for equivalent discrete-time loop architectures. I've always used step-invariant bilinear transforms to take the continuous time analyses to discrete-time with very good results. Other techniques seem to work as well, as long as one is consistent with the analysis and careful about assumptions. Hope that helps a little bit.
