4.4 Differential Input Cross Point Voltage
To guarantee tight setup and hold times as well as output skew parameters with respect to clock and strobe, each cross
point voltage of differential input signals (CK, CK and DQS, DQS) must meet the requirements in the following table. The
differential input cross point voltage Vix is measured from the actual cross point of true and completement signal to the
midlevel between of VDD and VSS.

4.5 Slew Rate Definitions for Single-Ended Input Signals
See “Address / Command Setup, Hold and Derating” for single-ended slew rate definitions for address and command
signals.

Extended range for Vix is only allowed for clock and if single-ended clock input signals CK and CK# are monotonic with a single-ended swing
VSEL / VSEH of at least VDD/2 +/-250 mV, and when the differential slew rate of CK - CK# is larger than 3 V/ns.
