... Two selectable independent LVCMOS compatible clock inputs are available, providing support of redundant clock source systems. The MPC9447 CLK_STOP control is synchronous to the falling edge of the input clock. It allows the start and stop of the output clock signal only in a logic low state, thus eliminating potential output runt pulses. Applying the OE control will force the outputs into high--impedance mode ...

... Termination Waveforms” show the simulation results of an output driving a single line versus two lines. In both cases, the drive capability of the MPC9447 output buffer is more than sufficient to drive 50Ω transmission lines on the incident edge. Note from the delay measurements in the simulations a delta of only 43ps exists between the two differently loaded outputs ...
