7 Parameter Measurement Information

GUID-20220401-SS0I-XNCQ-QQFC-PQ2JTXGDVXCH-low.png
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.
