NOTE 1: Measured from the differential input crossing point to the differential output crossing point.

NOTE 2: 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.

NOTE 3: This parameter is defined in accordance with JEDEC Standard 65.
