Hi,

My customer have question about the logic of the divider circuit of PFD.

A circuit of PFD is not a simple divider circuit from the following expression.

  PFDn Output Frequency = PLLx Output Frequency * (18/PFDn_FRAC) 

Q1)Please tell me about a logic of PFD in detail.

Best Regards,

soichi
