All parameters measured at f_MAX unless noted otherwise.
The cycle-to-cycle jitter on the input will equal the jitter on the output. The part does not add jitter
NOTE 1: Measured from the differential input crossing point to the differential output crossing point.
NOTE 2: Measured from V_CC/2 input crossing point to the differential output crossing point.
NOTE 3: Defined as skew between outputs at the same supply voltage and with equal load conditions.
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. Using the same type of inputs on each device, the outputs are measured
at the differential cross points.
NOTE 5: Please refer to the Phase Noise Plot.
NOTE 6: This parameter is defined in accordance with JEDEC Standard 65.
