6 Parameter Measurement Information
Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 ?, tt < 6 ns.
For clock inputs, fmax is measured when the input duty cycle is 50%.
The outputs are measured one at a time with one input transition per measurement.
(1) CL includes probe
and test-fixture capacitance.
