Notes on Electrical Characteristics:

1Guaranteed by design and characterization, not 100% tested in production.

2 Slew rate measured through Vswing centered around differential zero

3 Vxabs is defined as the voltage where CLK = CLK#

4 Only applies to the differential rising edge (CLK rising and CLK# falling)

6 All Long Term Accuracy and Clock Period specifications are guaranteed assuming that REFOUT is at 14.31818MHz

5 Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of

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

calculations.

7 Operation under these conditions is neither implied, nor guaranteed.

8 Maximum input voltage is not to exceed maximum VDD
