All parameters are measured at f ≤ 1GHz, unless otherwise noted.
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: Measured on Aeroflex PN9000.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65. Measured at the output differential cross points.
NOTE 5: 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.
