Output Duty Cycle

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.
