Dear Team,

 

We are using AD8062 Op-Amp to strip the sync information from the Red and Blue component. We have designed the circuit as per the recommended in the datasheet.

 

Please refer to the below fig.

 

Also I have added system block diagram

When I try to display this signal on RGsB monitor only Green component is getting display.

So I have checked the voltage levels,It is observed that Blue and Red voltage levels considerably lesser when compared to the Green.

I have attached the schematic also.

Please suggest the reason, why the voltage levels of the Blue and Red is less?

 

Regards,

Murali P T
