I want to use the LMX2572 to close the loop on data recovery using a software CDR. The output clock of the LMX2572 will be 5.625GHz +/- 100ppm. I will use software to increase/decrease the frequency until it is locked. I do realize that the loop time constant is very long, but this is fine. My question is whether the transition of up to +/-50ppm in frequency will be smooth or will it generate high jitter in the output at the time of transition. Assuming that I do not need to recalibrate within this +/-100ppm range.
