Jitter / Modulation Frequency (Hz)

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 5MHz the noise floor of this measurement is reached

but in reality, the attenuation continues with the 12dB/octave slope.
