I have a question about ADV7611.
Does ADV7611 have internal feedback resister in the oscillator circuit (XTALP, XTALN)?
Thank you!Best regards.
The internal circuit design isn't something we would generally discuss. What is the problem you are seeing?
Thank you for your reply.
We are not seeing any problem.But the customer is going to have external feedback resistor (1M ohm) between XTALP and XTALN on their boardif ADV7611 does not have internal feedback resistor in the oscillator circuit (XTALP, XTALN).So we want to know the information.Could you tell me whether there is internal feedback resistor or not?
We would rather not discuss the internal circuitry of the ADV7611.
I would strongly advise that your customer use the external 390 kOhm resistor between the XTALP/XTALN pins that is shown in the ADV7611 recommended schematic.
All evaluation of the ADV7611 was performed using the ADI recommended schematic.

Could you tell me whether ADV7611 has internal feedback resistor in XTALP, XTALN?
I asked the same question about ADV7181D before.Your question was "No, there is no internal resistor."http://ez.analog.com/thread/41083How about ADV7611?
