analog PLL and digital PLL

[chacha]

What is main difference between analog PLL and digital PLL??

 

[Btrend]

analog PLL : lower jitter value , easy to construct fully differential VCO to increase PSRR.
digital PLL : larger jitter value, hard to remove common mode noise (low PSRR)

classify by used pd/pfd

 

[khouly]

it mainly based on the PFD , if it's Mixer u can say it is analog PLL , the digital PLL use the PFD based digital circuits
