Notes :
1.
2.
Maximum burst refresh cycle : 8
The specific requirement is that DQS be valid(High or Low) on or before this CK edge. The case shown(DQS going from High_Z
to logic Low) applies when no writes were previously in progress on the bus. If a previous write was in progress, DQS could be
High at this time, depending on t
DQSS
.
3.
The maximum limit for this parameter is not a device limit. The device will operate with a great value for this parameter, but
system performance (bus turnaround) will degrade accordingly.
4.
5.
A write command can be applied with t
RCD
satisfied after this command.
For registered DIMMs, t
CL
and t
are
≥
45% of the period including both the half period jitter (t
JIT
(HP) ) of the PLL and the half
jitter due to crosstalk (t
JIT
(crosstalk) ) on the DIMM.

This derating table is used to increase t
/t
in the case where the DQ and DQS slew rates differ. The Delta Rise/Fall Rate is
calated as 1/SlewRate1-1/SlewRate2. For example, if slew rate 1 = 5V/ns and slew rate 2 =.4V/ns then the Delta Rise/Fall Rate =-
0/5ns/V. Input S/H slew rate based on larger of AC-AC delta rise/fall rate and DC-DC delta rise/fall rate.
10. This parameter is fir system simulation purpose. It is guranteed by design.
11. For each of the terms, if not already an integer, round to the next highest integer. t
CK
is actual to the system clock cycle time.
