DDR3L 1.35V Slew Rate Definitions for Single-Ended Input Signals
Setup (
t
IS and
t
DS) nominal slew rate for a rising signal is defined as the slew rate be-
tween the last crossing of V
REF
and the first crossing of V
IH(AC)min
. Setup (
t
IS and
t
DS)
nominal slew rate for a falling signal is defined as the slew rate between the last crossing
of V
REF
and the first crossing of V
IL(AC)max
.
Hold (
t
IH and
t
DH) nominal slew rate for a rising signal is defined as the slew rate be-
tween the last crossing of V
IL(DC)max
and the first crossing of V
REF
. Hold (
t
IH and
t
DH)
nominal slew rate for a falling signal is defined as the slew rate between the last crossing
of V
IH(DC)min
and the first crossing of V
REF
(see Figure 17 (page 48)).
