Slew Rate Definitions for Differential Input Signals<br />
Input slew rate for differential signals (CK, CK# and DQS, DQS#) are defined and measured,<br />
as shown in Table 31 and Figure 20. The nominal slew rate for a rising signal is<br />
defined as the slew rate between V IL,diff,max and V IH,diff,min. The nominal slew rate for a<br />
falling signal is defined as the slew rate between V IH,diff,min and V IL,diff,max.<br />
