7 Parameter Measurement Information
A. CL includes probe and test-fixture capacitance.
B. Phase relationships between waveforms were chosen arbitrarily. All input pulses
are supplied by generators having the following characteristics: PRR ≤ 1 MHz,
ZO = 50 Ω, tr = 6 ns, tf = 6 ns.
C. The
outputs are measured one at a time with one input transition per
measurement.
D. tPLH and tPHL are the same as tpd.
