Note that the JEDEC LPDDR2 specification (JESD209_2B) supersedes any specification in this document.
Vid(ac) specifies the input differential voltage |Vtr – Vcp| required for switching, where Vtr is the “true” input signal and Vcp is
the “complementary” input signal. The Minimum value is equal to Vih(ac) – Vil(ac).
The typical value of Vix(ac) is expected to be about 0.5  OVDD. and Vix(ac) is expected to track variation of OVDD. Vix(ac)
indicates the voltage at which differential input signal must cross.
