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.

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

VCC Vt RL CL ΔV
1.8V ± 0.15V VCC/2 1kΩ 30pF 0.15V
2.5V ± 0.2V VCC/2 500Ω 30pF 0.15V
2.7V 1.5V 500Ω 50pF 0.3V
3.3V ± 0.3V 1.5V 500Ω 50pF 0.3V
