Jitter Transfer
Jitter transfer or jitter attenuation refers to the magnitude of jitter at the output of a device for a given amount of jitter
at the input of the device. Input jitter is applied at various amplitudes and frequencies, and output jitter is measured
with various filters depending on the applicable standards.
For the MT90401, two internal elements determine the jitter attenuation. This includes the low pass loop filter and
the phase slope limiter. Both of these parameters have different settings depending on whether the device is in
