1. VCMR is the difference from the most positive side of the differential input signal. Normal operation is obtained when the “HIGH” input is within
the VCMR range and the input swing lies within the VPP specification.
2. The MPC953 outputs can drive series or parallel terminated (50
to VCC/2) 50 transmission lines on the incident edge (see Applications Info
section).
