Recently, we met a problem and needs your suggestion to find the root cause. As following picture , we used pattern generator that is built in ADV7393 has some problem in yellow bar. in the first , we doubt it might be the noise cause this problem, but after waveform measurement, we found out there is always an abnormal in same location (second page ,red column in the left, right side waveform is no this problem).
Per your experience, what is the reason cause this problem ,or what I can do to fix it ? thanks you very much!
