Notes:
1. V_REFac is equal to V_REFdc plus noise.
2. V_IH max and V_IL min apply for pulse widths less than one-quarter of the cycle time.
3. Input rise and fall times must be a minimum of 1 V/ns, and within 10% of each other.
4. Applies to: CK, CK, KD[1.0], KD[1.0], SA, D[35:0], R, W, ADZT1.
5. Applies to: DLL, RST, RLM[1:0], MZT[1:0], PZT[1:0].
