10.3 AC and DC Logic Input Levels for Differential Signals

10.3.1 Differential Signals Definition

Figure 2. Definition of differential ac-swing and "time above ac level" tDVAC

10.3.2 Differential Swing Requirement for Clock (CK-CK) and Strobe (DQS-DQS)

NOTE

1. Used to define a differential signal slew-rate.
2. for CK - CK use V

(AC) of ADD/CMD and V

REFCA

; for DQS - DQS use V

(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 they single-ended signals CK, CK, DQS, DQS need to be within the respective limits (V

(DC) max, V

(DC)min) for single-ended sig-

nals as well as the limitations for overshoot and undershoot. Refer to "overshoot and Undershoot Specification"

[ Table 3 ] Allowed time before ringback (tDVAC) for CK - CK and DQS - DQS.
