ADF5902 datasheet - INITIALIZATION SEQUENCE - ramp up 200MHz???

Hi I dont understand how to calculate the ramp up because in the example of initialization when I am calculating Fdev gives me this value:

DEV = 455 (step 27)

dev_offset = 9 (step 27)

Fpfd = 100MHz (step 37)

Fdev = (Fpfd / 2^25)*(DEV*(2^dev_offset)) = (100MHz /2^25)(455*(2^9))  = 0.6943MHz

# of steps = 144 (step 23)

so the total jump of frequency is:

# of steps * Fdev = 144*0.6943MHz = 100MHz

where are the 200MHz of ramp up???

thanks
