All parameters measured at fMAX unless noted otherwise.
NOTE 1: Measured from the differential input crossing point to the output at VDDO/2.
NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.
NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages,
with equal load conditions, and using the same type of inputs.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
