... All inputs have an internal pull-up or pull-down resistor preventing unused and open inputs from floating. The device supports a 2.5V or 3.3V power supply and an ambient temperature range of – +85 C. The MPC9449 is pin and function compatible but performance-enhanced to the MPC949. The device is packaged in a 52-lead LQFP package. ...

... I CCQ Maximum Quiescent Supply Current a The MPC9449 is capable of driving 50 transmission lines on the incident edge. Each output drives one 50 parallel terminated transmission line to a termination voltage Alternatively, the device drives up to two 50 series terminated transmission lines CMR (DC) is the crosspoint of the differential input signal. Functional operation is obtained when the crosspoint is within the V CMR range and the input swing lies within the V PP (DC) specification ...

Functional operation is obtained when the crosspoint is within the V CMR range and the input swing lies within the V PP (DC) specification. b The MPC9449 is capable of driving 50 transmission lines on the incident edge. Each output drives one 50 parallel terminated transmission line to a termination voltage Inputs have pull-down or pull-up resistors affecting the input current ...

... This suggests that the dual line driving need not be used exclusively to maintain the tight output-to-output skew of the MPC9449. The output waveform in Figure 4. “Single versus Dual Line Termination Waveforms” shows a step in the waveform, this step is caused by the impedance mismatch seen looking into the driver ...
