3.2.4 Differential Input AC logic Level
3.2.5 Differential AC output parameters
1. VIN(DC) specifies the allowable DC execution of each input of differential pair such as CK, CK, DQS, DQS,
2. VID(DC) specifies the input differential voltage |VTR -VCP | required for switching, where VTR is the true input
Note:
1. VID(AC) specifies the input differential voltage |VTR -VCP | required for switching, where VTR is the true input
2. The typical value of VIX(AC) is expected to be about 0.5 * VDDQ of the transmitting device and VIX(AC) is
Note:
1. The typical value of VOX(AC) is expected to be about 0.5 * V DDQ of the transmitting device and VOX(AC) is
