Characteristic
Measured at receiver.
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
is included to ensure margin for low frequency jitter, wander, noise, crosstalk, and other variable system effects.
