I have a question about ADV7181D.
Our customer change the Video-buffer to discrete to reduce the system cost.
Please see the circuit I attached.
After they change the Video-buffer to discrete, and input white-black repeat image(per 1sec)
the output look like flashing.
=> Please see the video I attached.
The left side display is the ADV7181D output.
Our customer want to know why this happen when they change the circuit.
Can you give me some advice about this?
I think , maybe the current bias is to low when they use discrete.
If you can give us some advise, it will help us and our customer very much.
