Jitter / Modulation Frequency (Hz)
1.E+06
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.
