My ADC System is as follows:
50 Ohm terminated input signal -(differential)-> AD8138 -(differential)-> AD9244-40.
The ADC runs at 16 Mhz, it has only a simple low-pass input filter (2 x 33R, 22pF).
Data conversion generally works, but i get wrong output data from time to time (please see attached pictures).
1.) This has nothing to do with aliasing, right? --> a more complex input filter would not help.
2.) It is more likely that some clock interferes?
