IMX7 ADC VREF

I'm trying to figure out what the VREF for the ADCs is. It is mentioned in table 89 in the datasheet for specifying the input voltage but I can't find the specification for VREF itself.

 

I'm also looking for some specification from which I can calculate my maximum input impedance. This must have something to do with sample rate etc. as this is ultimately and RC coupling that needs to be charged/discharged. I only intend to measure dc-voltages.
