(2) The total residual jitter at BER-12 was calculated as DJ+14.1xRJ, where DJ is deterministic jitter and RJ is random jitter. The jitter is
expressed as a portion of a unit interval (UI). One UI is a reciprocal of a bit rate (or data rate). For example, a 1.5 Gbps (gigabit per
second) signal has 1 / (1.5 Gb/s) = 666.67 ps (picosecond) unit interval. A 0.25 UI jitter is equivalent to 0.25 x 666.67 ps = 166.67 ps.
