what is the relation b/w Loop BW and other parameters of PLL.

Re: Charge pump PLL

Hi
Loop BW is mainly determined by PLL loop filter.
Loop BW directly affect the settling time of the PLL
Based on the PLL TYPE and ORDER, loop BW has its effect on PLL stability.


Thanks

Charge pump PLL

1 To minimize output phase jiffter due to external noise ,the loop bandwidth should be made as narrow as possible.
2 To minimize transient error due to signal modulation , to minimize output jitter due to internal oscillator noise ,or to obtain best tracking and acquisition properties,the loop bandwidth should be made as wide as possible.

Could you tell me where can I get F.M Gardner's PLL book??
