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. The MPC9449 is capable of driving 50 transmission lines on the incident edge. Each output drives one 50 parallel terminated
transmission line to a termination voltage of VTT.
3. Inputs have pull-down or pull-up resistors affecting the input current.

1. AC characteristics apply for parallel output termination of 50 to VTT.
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.
3. An input rise/fall time greater than that specified may be used, but AC characteristics are not guaranteed under such a condition.
