8 Parameter Measurement Information
In the below images, VCCI and
VCCO refers to the power supplies VIO and VISOIN,
respectively.
A. CL = 15 pF and The
input pulse is supplied by a generator having the following characteristics: PRR
≤ 50 kHz, 50% duty cycle, tr ≤ 3 ns, tf ≤ 3ns,
ZO = 50 Ω. At the input, 50 Ω resistor is required to terminate
Input Generator signal. It is not needed in actual application.
B. B. CL = 15 pF and
includes instrumentation and fixture capacitance within ±20%.
