The MPC9443 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 V
CC =2.5 V).

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.
