MPC93R51 Data Sheet
LOW VOLTAGE PLL CLOCK DRIVER
Figure 8. Single versus Dual Waveforms
Since this step is well above the threshold region it will not
cause any false clock triggering; however, designers may be
uncomfortable with unwanted reflections on the line. To better
match the impedances when driving multiple lines, the
situation in Figure 9 should be used. In this case, the series
terminating resistors are reduced such that when the parallel
combination is added to the output buffer impedance, the line
impedance is perfectly matched.
