Notes:
6.
High-frequency AC-parameters are guaranteed by design and characterization.
7.
Measured from VCC/2 of the input to the differential output crossing point.
8.
Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the output differential cross points.
9.
Defined as skew between outputs on different devices operating at the same supply voltages and with equal load conditions. Using the same type
of inputs on each device, the outputs are measured at the differential cross points.
