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.

Max

Defined by

Differential input slew rate for rising edge

(CK-CK and DQS-DQS)

VILdiffmax VIHdiffmin [VIHdiffmin-VILdiffmax] / DeltaTRdiff

Differential input slew rate for falling edge

(CK-CK and DQS-DQS)

VIHdiffmin VILdiffmax [VIHdiffmin-VILdiffmax] / DeltaTFdiff

Notes:

The differential signal (i.e. CK-CK and DQS-DQS) must be linear between these thresholds.
