VCMR(1)
1. VCMR (DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the VCMR range
and the input swing lies within the VPP (DC) specification.

2. VCMR (AC) is the crosspoint of the differential input signal. Normal AC operation is obtained when the crosspoint is within the VCMR range
and the input swing lies within the VPP (AC) specification. Violation of VCMR or VPP impacts propagation delay.
