11.3.3 Single-ended Requirements for Differential Signals

Each individual component of a differential signal (CK, DQS, CK, DQS) has also to comply with certain requirements for single-ended signals.
CK and CK have to approximately reach V

SEH

min / V

SEL

max (approximately equal to the ac-levels ( V

(AC) / V

(AC) ) for ADD/CMD signals) in every

half-cycle.
DQS, DQS have to reach V

SEH

min / V

SEL

max (approximately the ac-levels ( V

(AC) / V

(AC) ) for DQ signals) in every half-cycle proceeding and follow-

ing a valid transition.
Note that the applicable ac-levels for ADD/CMD and DQ’s might be different per speed-bin etc. E.g. if V

150(AC)/V

150(AC) is used for ADD/CMD

signals, then these ac-levels apply also for the single-ended signals CK and CK .

Figure 4. Single-ended requirement for differential signals

Note that while ADD/CMD and DQ signal requirements are with respect to V

REF

, the single-ended components of differential signals have a requirement

with respect to V

/2; this is nominally the same. The transition of single-ended signals through the ac-levels is used to measure setup time. For single-

ended components of differential signals the requirement to reach V

SEL

max, V

SEH

min has no bearing on timing, but adds a restriction on the common

mode characteristics of these signals.

[ Table 6 ] Single ended levels for CK, DQS, CK, DQS

NOTE

1. For CK, CK use V

(AC) of ADD/CMD; for strobes (DQS, DQS) use V

(AC) of DQs.

2. V

(AC)/V

(AC) for DQs is based on V

REFDQ

; V

(AC)/V

(AC) for ADD/CMD is based on V

REFCA

; 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, 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"
