Notes:
1. The peak-to-peak AC component superimposed on V_REF may not exceed 5% of the DC component of V_REF.
2. Performance is a function of V_IH and V_IL levels to clock inputs.
3. See the AC Input Definition diagram.
4. See the AC Input Definition diagram. The signals should swing monotonically with no steps rail-to-rail with input signals never ringing back past
V_IH (AC) and V_IL (AC) during the input setup and input hold window. V_IH (AC) and V_IL (AC) are used for timing purposes only.
