What is Jitter?

Hello,

This is a basic question.

According to ADuM6212 data sheet (of course not only this device), there is a Jitter value in Table 5. switching specifications.

Where is this Jitter come from? Is this a periodical jitter?

I cannot find any definition of this Jitter specification.

Thank you for your help as always.

Best regards,

  • Tatsuya: Jitter in our devices is a measurement of the variation of the propagation delay, which is a skew of the input waveform and the output waveform as viewed on the scope over a period of time.  Jitter can be random jitter or deterministic jitter, but most of the jitter is deterministic.  The deterministic jitter can be periodic, data dependent or duty cycle jitter (pulse width distortion).  The jitter referred to in the datasheet is periodic or data dependent.
