newic Senior Member Offline Posts: 138	self-bias PLL vs ICO PLL Mar 21^st, 2012, 8:14pm self biased PLL is widely used but the jitter performance is not that good if compare to ICO type PLL (better PSRR). Is it true and why?

If so you are wrong because self bias pll is based on CCO (may be some people cal this is regulator based vco). Thanks, Raj.
