7.9 Propagation Delay

Propagation delay is defined as the time taken by the output of the device to rise or fall 50% after the input signal

has risen or fallen past the 50% threshold. Figure 35 shows the setup used to measure propagation delay,

denoted by the symbol tPD.

7.10 Skew

Skew is defined as the difference between propagation delays of any two outputs of the same device. The skew

measurement is taken from the output of one channel rising or falling past 50% to a second channel rising or

falling past the 50% threshold when the input signals are switched at the same time. Figure 36 shows the setup

used to measure skew, denoted by the symbol tSK.
