since MASH 1-1-1 output from -4 to 3, the integer divided number is C, and the output frequency of VCO is Fout (assume Fout is 960MHz)

Is (Fout/(C-4) - Fout/(C+3))/C the VCO output frequency shift?

since the frequency shift should less than 200kHz*x (x<1), assume x=0.01,

so C should be large than 170 and then reference frequency cannot be 26MHz

do I calculate correct?
