I am currently reviewing the ADF4112 fVCO. We would like to study if we can simulate the FSK feature in ADF4112
Following equation is the VCO frequency:
fVCO = [(P × B) + A] fREFIN/R
Output frequency is generated by A&B counter, R divider and P prescaler.
Assume FREFIN fixed, could we can simulate FSK frequency shift feature by changing parameter?
Like intermittent programming LATCH value, such as P prescaler. I check the timing diagram and it should be feasible.
Appreciate if you have any advice.
