My current architecture is HDMI source-->ADV7612 --> ADV8005 --> scaler,
When there is no input HDMI signal, I enable ADV7612 freerun for ADV8005 OSD display,
We have a question, the scaler IC can generate H sync, V sync, and DE signal.
If we only need OSD, no need input signal, we consider to remove ADV7612.
Is it possible use scaler H sync, V sync, and DE signal for ADV8005 reference clock so that ADV8005 can display OSD?
What signals are necessary for ADV8005 reference clock to display OSD (1080P OSD)?
