Jitter / Modulation Frequency (Hz)
1.E+07
The jitter attenuation works like a low-pass filter for frequency modulated signals or noise. The bandwidth for this low
pass filter is 500kHz with a 12dB/octave slope above 500kHz. At about 6MHz the noise floor of this measurement is
reached but in reality, the attenuation continues with the 12dB/octave slope.
Phase noise performance with a clean input clock:
156.25MHz with 55fsRMS for phase jitter for 1.875MHz to 20MHz integration range
156.25MHz with 251fsRMS for phase jitter for 12kHz to 20MHz integration range
