Minimum Divider Value for HMC703

With a 100M Ref, what is the lowest N value I can use in the HMC703 PLL IC to lock to 500M, 1000M and 1500M at VCO input? Per data sheet, min N =16; so this implies I would need 25M, 50M and 50M at the phase freq detector by dividing the 100Ref input by 2 and 4.

 

I do not need continuous coverage. It would suffice to leave Ref Counter R=1 ; the PFD freq =100MHz, and program N=5, 10 and 15.
