Hello.

 

I have a question about end termination of 75 Ohms of AIN pin of ADV7181D.

 

When 1.0Vp-p signal is AC coupled and inputted into AIN pin of ADV7181D,
is it no problem without end termination of 75 Ohms?
Please refer attached file "Without_75ohm_termination_for_AIN.pptx".

 

Is the end termination of 75 Ohms used for ONLY the purpose to be approximately half the inputted video signal voltage to the video decoder?

 

Thank you!
Best regards.
