Notes:
1. For input only pins except RESET#. Vref = VrefDQ(DC)
2. See "Overshoot and Undershoot Specifications"
3. The ac peak noise on Vref may not allow Vref to deviate from Vref(DC) by more than ± 1.0% VDD.
4. For reference: DDR3 has approx. VDD/2 ±15mV, and DDR3L has approx. VDD/2 ± 13.5mV.
5. Single-ended swing requirement for DQS-DQS#, is 350mV (peak to peak). Differential swing requirement for DQS-DQS#, is 700mV (peak to peak)
