Hello,
I need to know how to determine the bandwith limits of a 800Mhz PLL having using a 50Mhz reference clock.
Actually I have a digital circuits using a 800Mhz (period =1250ns) clock signal for synchronization. By simulation I measured the maximum (1270ns) and minimum (1220ns) clocks period variation making the circuit unfunctional.
The maximum jitter supported by is 30ps (or 60 ps peak to peak). How to understand this in terms of bandwith and Phase margin limits ?
Regards,
