Differential Input Slew Rate Definition
Input slew rate for differential signals (CK, CK# and DQS, DQS#) are defined and
measured, as shown in Table 28 and Figure 23. The nominal slew rate for a rising signal
is defined as the slew rate between V
rate for a falling signal is defined as the slew rate between V
