8 / 23 page 7 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 Ω, tt < 2.5 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. CL (1) From Output Under Test Test Point (1) CL includes probe and test-fixture capacitance. Figure 7-1.
