1) Timings are guaranteed with CK/CK differential Slew Rate of 2.0 V/ns. For DQS signals timings are guaranteed with a differential Slew
Rate of 2.0 V/ns in differential strobe mode and a Slew Rate of 1 V/ns in single ended modeTimings are further guaranteed for normal
OCD drive strength (EMRS(1) A1 = 0)
2) The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross. The DQS / DQS, RDQS / RDQS,
input reference level is the crosspoint when in differential strobe mode.
3) Inputs are not recognized as valid until
V
REF
stabilizes. During the period before
V
REF
stabilizes, CKE = 0.2 x
V
DDQ
is recognized as low.
4) The output timing reference voltage level is
