TIMING SOLUTIONS
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 7 “Optimized Dual Line Termination” 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.
