NOTE 1: Measured from the differential input crossing point to VDDO/2 of the output.

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

Measured at VDDO/2.

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 VDDO/2.

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