DQS to DQ output timing is shown in Figure 77 (page 162). The DQ transitions be-
tween valid data outputs must be within
DQS must also maintain a minimum HIGH and LOW time of
the READ preamble, the DQ balls either will be floating or terminated depending on the
status of the ODT signal.
Figure 78 (page 163) shows the strobe-to-clock timing during a READ. The crossing
point DQS, DQS# must transition within ±
out has no timing relationship to clock, only to DQS, as shown in Figure 78 (page 163).
Figure 78 (page 163) also shows the READ preamble and postamble. Typically, both
DQS and DQS# are High-Z to save power (V
DQS is driven LOW and DQS# is HIGH for
The READ postamble,
ing the READ postamble, DQS is driven LOW and DQS# is HIGH. When complete, the
DQ will either be disabled or will continue terminating depending on the state of the
ODT signal. Figure 83 (page 167) demonstrates how to measure
