HMC807 Phase Detector frequency

HMC807 Question:

My reference is 10MHz sinewave,What is the Phase detector Frequency?

10MHz sinewave is ok for HMC807?

  • Hi there,

    Phase Detector freq = Reference Freq / R Divider so if RDIV = 1 then REF frequency = PD Frequency. PD Frequency can not exceed reference frequency. In the case of our integrated VCO / PLL products the reference frequency will  always be an integer multiple of the phase detector frequency. 

    Ian Collins put together a nice primer on PLL basics. Please see attached.
