1. Total jitter is composed of three components, deterministic jitter, random jitter and single frequency sinusoidal jitter. The
sinusoidal jitter may have any amplitude and frequency in the unshaded region of Figure 59. The sinusoidal jitter component
is included to ensure margin for low frequency jitter, wander, noise, crosstalk and other variable system effects.
