C and with a 3.3-V supply.
t
sk(p)
is the magnitude of the time difference between the t
and t
of any output of a single device.
t
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.
Jitter is specified by design and characterization. Stimulus jitter has been subtracted.
