6 Parameter Measurement Information

Phase relationships between waveforms were chosen arbitrarily for the examples listed in the following table. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1MHz, ZO = 50Ω, tt < 2.5ns.

For clock inputs, fmax is measured when the input duty cycle is 50%.

The outputs are measured individually with one input transition per measurement.
