wat is design consideration of designin a PLL synthesiser.. how diff it is from designing a PLL for tracking
 

Re: PLL synthesizer

Basically not much difference. However PLL for tracking will have more resource contraints and hence some performance will be compromised.

Re: PLL synthesizer

i think it is not much different
but for syn , we concentrate on phase noise and spectral purity of VCO
so we must compromise between the nose from reff osc and VCO

in tracking pll , u need that the VCO , produce the carrier again , so the bandwidth of the pll is chosen to be small to clean the noise included in the signal u want to track "this is also valid for clock recovery "
