7.8 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 34 shows the setup used to measure skew, denoted by the symbol t_SK.
