All parameters measured at f_MAX unless noted otherwise.
Special thermal considerations may be required. See Applications Section.
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.
NOTE 3: This parameter is defined in accordance with JEDEC Standard 65. Measured at the output differential cross points.
NOTE 4: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load conditions at
the same temperature. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
NOTE 5: Driving only one input clock.
