|LEGEND: R/W = Read/Write; R = Read only; -n = value after reset|
|RAMP_THRESH||R/W||0||This sets how much the ramp can change the VCO frequency before calibrating. If this frequency is chosen to be Δf, then it is calculated as follows:
RAMP_THRESH = (Δf / fPD) × 16777216
|R78||QUICK_RECAL_EN||R/W||0||Causes the initial VCO_CORE, VCO_CAPCTRL, and VCO_DACISET to be based on the last value. Useful if the frequency change is small, as is often the case for ramping.
|R78[8:1]||VCO_CAPCTRL_STRT||R/W||0||This sets the initial value for VCO_CAPCTRL if not overridden by other settings. Smaller values yield a higher frequency band within a VCO core. Valid number range is 0 to 183.|
