Notes:
1. Pins B3 and A2 have identical capacitance as pins B7 and A8.
2. For a read, when enabled, strobe pair RDQS & RDQS are identical in function and timing to strobe pair DQS
& DQS and input masking function is disabled.
3. The function of DM or RDQS/RDQS are enabled by EMRS command.
4. VDDL and VSSDL are power and ground for the DLL.

Notes:
1. VID(AC) specifies the input differential voltage |VTR -VCP | required for switching, where VTR is the true input signal (such as CK, DQS,
LDQS or UDQS) and VCP is the complementary input signal (such as CK, DQS, LDQS or UDQS). The minimum value is equal to VIH(AC)
- VIL(AC).
2. The typical value of VIX(AC) is expected to be about 0.5 * VDDQ of the transmitting device and VIX(AC) is expected to track variations
in VDDQ . VIX(AC) indicates the voltage at which differential input signals must cross.
