Jitter and phase noise conversion?
May 09th, 2009, 7:27pm
 
 Hi guys
 I found a jitter and phase noise conversion equation from Page 146, book "The Design of Low Noise Oscillators", Jitter=sqrt(1/f).(delta_omega/Omega_center).10^(L(delta)omega)/20).
So for a center frequency of 2GHz, phase noise is 100dBc/Hz at 1MHz, the jitter will be sqrt(1/2e9)*(1e6/2e9)*10^(100/20)=0.11ps jitter, am I right?
 Or there has some other ways to do this conversion. Thank you for your help.

Hi liletian,

that is only true if your osc has only white noise and the pahse noise is exactly -20db/dec.
