1. VCMR is the center of the differential input signal. Normal operation is obtained when the input crosspoint is within the VCMR range and the input
swing lies within the VPP specification.
2. The MPC958 outputs can drive series or parallel terminated 50
Ω (or 50Ω to VCC/2) transmission lines on the incident edge (see Applications
Info section).
