    sigma delta fractional n pll

    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?

    Can Delta-Sigma replace Accumulator in Fraction-N PLL?

    Can you explain clearly? Many papers saidthat the The Delta-Sigma input is fractional code,and it can't be the swallow out.

    fractional-N vs integer-N frequency synthesizer?

    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? Added after 22 seconds: Now my team is going on a...
