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.

Notes:
1. 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.
