a) What is a typical PLL filter composed from? b) What is it's purpose in the PLL circuit? Is it a lowpass to filter out the phase error signal? c) What is a typical PLL solution if I want to say make 100MHz from 33.3MHz? d) What if I want to make 44.1kHz from say 33MHz and need it super-hyper-roxx0r stable because am using it for feeding Hi-Fi audio DAC and even the tiniest jitter would be audible? How do I do it with PLL? Cl<
