1. AC characteristics are design targets and pending characterization.
2. V_PP is the minimum differential input voltage swing required to maintain AC characteristics including t_PD and device-to-device skew.
3. V_CMR (AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the V_CMR (AC)
range and the input swing lies within the V_PP (AC) specification. Violation of V_CMR (AC) or V_PP (AC) impacts the device propagation delay,
device and part-to-part skew.
