Unit Interval
Signaling convention that is binary and unidirectional. In this binary signaling, one bit
is sent for every edge of the forwarded clock, whether it be a rising edge or a falling
edge. If a number of edges are collected at instances t1, t2, tn,...., tk then the UI at
instance “n” is defined as:
UI n = t n – t n – 1
