8.0 AC & DC Input Measurement Levels
8.1 AC and DC Logic input levels for single-ended signals
[ Table 7 ] Single Ended AC and DC input levels for Command and Address
Note :
1. For input only pins except RESET, V
2. See 9.6 "Overshoot and Undershoot specifications"
3. The AC peak noise on V
4. For reference : approx. V
[ Table 8 ] Single Ended AC and DC input levels for DQ and DM
Note :
1. For input only pins except RESET, V
2. See "Overshoot and Undershoot specifications".
3. The AC peak noise on V
4. For reference : approx. V
5. Single ended swing requirement for DQS - DQS is 350mV (peak to peak). Differential swing for DQS - DQS is 700mV (peak to peak).
