components are included in this requirement. The reference impedance for return loss measurements is
100-
Ω resistive for differential return loss and 25-Ω resistive for common mode.

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 55. The sinusoidal jitter component
is included to ensure margin for low frequency jitter, wander, noise, crosstalk and other variable system effects.
