Overshoot/Undershoot specification
AC Operating Conditions
Note 1. VID is the magnitude of the difference between the input level on CK and the input on CK.
Notes 1. Includes ± 25mV margin for DC offset on V
Maximum peak amplitude allowed for overshoot
Maximum peak amplitude allowed for undershoot
The area between the overshoot signal and VDD must be less than or equal to
The area between the undershoot signal and GND must be less than or equal to
Input High (Logic 1) Voltage, DQ, DQS and DM signals
