(1) Typical values are at room temperature and with a V
CC
of 3.3 V.
(2) Part-to-part skew is the magnitude of the difference in propagation delay times between any specified terminals of two devices when
both devices operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
(3) Period jitter is the deviation in cycle time of a signal with respect to the ideal period over a random sample of 100,000 cycles.
(4) Cycle-to-cycle jitter is the variation in cycle time of a signal between adjacent cycles, over a random sample of 1,000 adjacent cycle
pairs.
