Phase relationships between waveforms
were chosen arbitrarily for the examples listed in the following table. All input
pulses are supplied by generators having the following characteristics: PRR ≤ 1MHz,
ZO = 50Ω, tt < 2.5ns.
The outputs are measured individually
with one input transition per measurement.
(1) CL includes probe
and test-fixture capacitance.

greater between tPLH and tPHL is the same as
tpd.
