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 voltage and with equal load conditions.
Measured at the differential output crosspoints.
NOTE 3: Defined as skew 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 crosspoints.
NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.
