NOTE:

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 16. The sinusoidal jitter component is included to ensure margin for low frequency jitter,

wander, noise, crosstalk and other variable system effects.
