Definitions for test circuit:
R
L
= Load resistance.
C
L
= Load capacitance including jig and probe capacitance.
R
T
= Termination resistance should be equal to the output impedance Z
O
of the pulse generator.
t
f
= 6 ns; when measuring f
max
, there is no
constraint to t
r
and t
f
with 50% duty factor.
