Note:
Table 11 on page 23 and Table 12 on page 24 define the address, command, and data
setup and hold derating values. These values are added to the default
t
the 2 V/ns the nominal setup and hold specifications are based upon.
To determine the setup and hold time needed for a given slew rate, add the
default specification to the “
specification to the “
derated data setup and hold values can be determined in a like manner using the “
V
The derating values on Table 11 and Table 12 apply to all speed grades.
The setup times on Table 11 and Table 12 represent a rising signal. In this case, the time
from which the rising signal crosses V
must be maintained across all slew rates. The derated setup timing represents the point
at which the rising signal crosses V
is calculated by determining the time needed to maintain the given slew rate and the
delta between V
Table 12 are also valid for falling signals (with respect to V
cross point).
The hold times in Table 11 and Table 12 represent falling signals. In this case, the time
from the CK/CK# cross point to when the signal crosses V
be maintained across all slew rates. The derated hold timing represents the delta
between the CK/CK# cross point to when the falling signal crosses V
value is calculated by determining the time needed to maintain the given slew rate and
the delta between the CK/CK# cross point and V
Table 12 are also valid for rising signals (with respect to V
CK# cross point).
