Table 3. Absolute Maximum Ratings(1)
1. Absolute maximum continuous ratings are those maximum values beyond which damage to the device may occur. Exposure to these
conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation at absolute-maximum-rated
conditions is not implied.

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.

3. The MPC9448 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. Alternatively, the device drives up to two 50 series terminated transmission lines
(for VCC = 3.3 V) or one 50 series terminated transmission line (for VCC = 2.5 V).
