MPC9456 Summary of contents
Page 1
... The clock input is low voltage PECL compatible for differential clock distribution support. Please consult the MPC9446 specification for a full CMOS compatible device. For series terminated transmission lines, each of the MPC9456 outputs can drive one or two traces giving the devices an effective fanout of 1:20. The device is packaged in a 7x7 mm 2 32-lead LQFP package. ...

... This suggests that the dual line driving need not be used exclusively to maintain the tight output-to-output skew of the MPC9456. 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 ...
