All parameters measured at 500MHz unless noted otherwise.
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 voltages and with equal load conditions.
Measured from at the output differential cross points.
NOTE 3: Defined as skew within a bank of outputs at the same voltages and with equal load conditions.
NOTE 4: Defined as 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 the differential cross points.
NOTE 5: This parameter is defined in accordance with JEDEC Standard 65.
