We are designing a board similar to circuit diagram
(RevD) Figure 89. ADV7342/ADV7343 Typical Application Circuit
We are output a NTSC interfaced and we see that there is yellow noise all over the output .
Place where we are not output , we have set it output as Black , but on the display we see yellow lines .
Please let me know if you have information with regards to this issue .
With best regards and wishes
