1:10 LVCMOS ZERO DELAY CLOCK 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
be used. In this case the series terminating resistors are re-
duced such that when the parallel combination is added to
the output buffer impedance the line impedance is perfectly
matched.
