(1) All typical values are at 25°C and with a 3.3-V supply.
(2) t
sk(p)
is the magnitude of the time difference between the t
PLH
and t
PHL
.
(3) t
sk(pp)
is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both
devicesoperate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
(4) Jitter parameters are ensured by design and characterization. Measurements are made with a Tektronix TDS6604 oscilloscope
runningTektronix TDSJIT3 software. Agilent E4862B stimulus system jitter 2 ps t
