Notes:
1. Used to define a differential signal slew-rate.
2. For CK - CK# use V IH.CA(AC) /V IL.CA(AC) of ADD/CMD and V REFCA ; for DQSL, DQSL#, DQSU , DQSU# use
V IH.DQ(AC) /V IL.DQ(AC) of DQs and V REFDQ ; if a reduced AC-high or AC-low level is used for a signal group, then the
reduced level applies also here.
3. These values are not defined; however, the single-ended signals CK, CK#, DQSL, DQSL#, DQSU, DQSU# need to be within
the respective limits (V IH(DC) max, V IL(DC)min ) for single-ended signals as well as the limitations for overshoot and
undershoot. Refer to section 10.12 “ Overshoot and Undershoot Specifications ” on page 121.
