Found three different versions for time<->db jitter formula - - 20log(1/2piFJ) Jitter in a Nutshell: "Whole Lotta Shakin' Goin' On"? - 20log(Jw/4) where w is the angular freq meaning 2piF cMP² | CMP / 03Jitter - And same as above except w is just freq in Hz. Jitter explained - Part 1.4 [English] Each would obviously yield a different result so which one is correct ?
