Table 7 lists CPM output characteristics.
Table 8 lists CPM input characteristics.
Note that although the specifications generally reference the rising edge of the clock, the following AC
timing diagrams also apply when the falling edge is the active edge.

Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal.
Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge of CLKIN.
Timings are measured at the pin.
