please tell me about when do not use the following pin.
does it have done what processing?
All these pins are output pins. They can be left floating or unconnected if they are not being used.
There is material that I want you to offer.
Please send IBIS or SPICE.
We don't have an ibis file for the ADV7188 however you can extract some of the parameters from the ADV7189 ibis file found at this link.
About a voltage output pin of the built-in reference, Please tell me a method of use.
Please tell me the electrical specifications of the REFOUT pin.
Does this have a mention to a data sheet?
I am going to forward this the the ADV7188 expert.
The REFOUT pin should only be connected as described in the datasheet. The external filtering capacitors are required for the internal reference to operate correctly.
No other circuitry should be connected to this pin.
This voltage reference is set internally as part of the ADI recommended settings.
Changing the voltage reference or adding external noise to this pin will affect the ADC performance.
