Below is what I found in google. But does not explain much to me...

SJ (Sinusoidal Jitter):
Sinusoidal Jitter has a periodic form and is related to (engendered by) the data patterns in the system. Sinusoidal Jitter is a component of the Deterministic Jitter.


many thanks.

Added after 19 minutes:

someone said that sinusoidal jitter is period jitter? right or wrong?

For a simple concept, there are many misconceptions about what exactly jitter is, and its definition varies depending on whom you ask.
Jitter is commonly defined as “The deviation from the ideal timing of an event".

..

Periodic jitter is another term for sinusoidal jitter.

jitter of a sine wave represents the variation in its zero crossing in the time domain.

this corresponds to phase noise in frequency domain.

"component of the Deterministic Jitter", jeez someone please shoot the knurds!

Sinusoidal jitter is time jitter caused by something repeatable, like noise from a switching power supply or noise caused by mechanical vibration (a fan running at a certain speed, an antenna tower vibrating in the wind), etc.
