Table 4–116. DQS Phase Offset Delay Per Stage (ps)
DQS
This skew specification is the absolute maximum and minimum skew. For
example, skew on a 40 DQ group is 40 ps or 20 ps.
The delay settings are linear.
The valid settings for phase offset are -32 to +31.
The typical value equals the average of the minimum and maximum values.
