3.3V, 2.5V, 1:9 LVCMOS CLOCK FANOUT BUFFER
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 6
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.
