AC Timing Parameters
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 mode. For other
Slew Rates see Chapter 8. Timings are further guaranteed for normal OCD drive strength (EMRS(1) A1 = 0) under the
“Reference Load for Timing Measurements” according to Chapter 8.1 only.
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; The input reference level for signals
other than CK/CK, DQS/DQS, RDQS/RDQS is defined in Chapter 8.3.
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
V
TT
. See section 8 for the reference load for timing measurements.
5)
t
RAS.MAX
is calculated from the maximum amount of time a DDR2 device can operate without a refresh command which is
equal to 9 x
t
REFI
.
