Slew Rate Definitions for Differential Input Signals
Input slew rate for differential signals (CK, CK and DQS, DQS) are defined and measured as shown in table
and Figure below.
and Figure below.
Notes:
The differential signal (i.e. CK-CK and DQS-DQS) must be linear between these thresholds.
The differential signal (i.e. CK-CK and DQS-DQS) must be linear between these thresholds.
