PLL BW, jitter etc
It depends on...
There are some parameters which influence the performance you have said.
jitter: if your system's noise mainly from vco, then a larger BW helps to reduce the jitter; the setting of BW is a trade-off with the vco phase noise and the reference noise(divider noise or sdm quantization noise, etc)
Lock time: lock time is inversely proportional to the BW and damping factor.
Stability: Roughly, the larger BW, the poor stability...
the tool "PLL design asistant" mengcy mentioned above is a very good PLL behavior simulation tool.
you can find it from Dr.Perrott's group.
