The clock-correction seemed a bit crude. I expected to find a PI-filter and a phase-accumulator to steer the 300 MHz to 37 MHz synthesis. Actually I do use a phase accumulator, in Fig. 26 it's inside the binary search block. The phase is accumulated during several seconds (longer for a noisy

Hi Attila Thanks for the feedback. * you have a lot of simulation and measurments on BER vs SNR. For time-nutty needs that's not so relevant. An ADEV plot would be much more informative on the stability. * Also some data on the absolute timing variations vs time would be nice to have. Yes
