Part Number: LMH1983
It was found in LMH1983 prototype, that TOF2/3/4 can not detected, but PLL1/2/3/4 are all locked.
Would you help analysis this issue? As TOF2/3/4 are used for external LED indicators. In circuit, D18 LED is off, D17 and D19 are on.
Adding some pictures in case they were missing in questions
In reply to Rocky Chen:
Are they providing H, V, F sync inputs?
Did they follow the TOF alignment programming steps in datasheet sections 8.3.10-8.3.12?
In reply to Alan O:
Yes, there is H,V,F sync input provided, and customer followed the section of 8.3.10-8.3.12. But the issue is still there.....Any other clue or ways we can try?
