Does here someone have worked for multiple bit Σ△frctional n pll?
I want to know if there is a multi bit Σ△ modulator is used in fractional n pll, then you must have a multi modulus divider?
and how the control circuit realization between the multi bit Σ△ modulator and multi modulus divider?
wideband dds frequency synthesizer
Now my team is go on a project about 802.15.4 based on 2.4G band. The channel space is 5M. Is Integer-N good or Fractional-N good?
if the Fractional-N is good,how can i decide the reference frequency?
