I would like to retrieve some information on how the VTUNE voltage changes with low frequency phase changes on the input to the ADF4371. I noticed there is a built in ADC to do just that! I don't see any information on the ADC in the datasheet, asides from the temperature readback appnote. Can I get more information on how to detect slight changes in the VTUNE voltages, (LF, <1MHz variations)? I noticed there is continuous conversion mode, Fast Conversion mode, etc. Can you detail what these modes do? I can assume what continuous is, but not Fast conversion. In the meantime I will try and use the Temp readback appnote to get some useable information out of the device.
