CLK and falling edge of CLK#. It is measured using a +/-75mV window centered on the average cross point where CLK meets
CLK#. The average cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate

Notes on Electrical Characteristics:
Electrical Characteristics - REF-14.318MHz
Guaranteed by design and characterization, not 100% tested in production.
Slew rate measured through Vswing centered around differential zero
Vxabs is defined as the voltage where CLK = CLK#
Only applies to the differential rising edge (CLK rising and CLK# falling)
Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of
All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz
Operation under these conditions is neither implied, nor guaranteed.
Maximum input voltage is not to exceed maximum VDD
