a.

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.

b.

The MPC9351 is capable of driving 50

Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated transmission line

to a termination voltage of VTT. Alternatively, the device drives up to two 50Ω series terminated transmission lines per output.

b.

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 static phase offset t(

∅).
