All parameters measured at 133MHz unless noted otherwise.
NOTE 1: Measured from the 50% point of the input 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..
