All parameters measured at IJ 650MHz unless noted otherwise.

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

NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.

Measured at the output differential cross points.

NOTE 3: 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 4: This parameter is defined in accordance with JEDEC Standard 65.
