can be useful when driving long trace lengths on less critical
networks.

Figure 27. CMOS Output with Far End Termination
Because of the limitations of single-ended CMOS clocking,
consider using differential outputs when driving high speed
signals over long traces. The ADCLK854 offers LVDS outputs
that are better suited for driving long traces wherein the inherent
noise immunity of differential signaling provides superior
performance for clocking converters.
INPUT TERMINATION OPTIONS
For single-ended operation always bypass unused input to
GND, as shown in Figure 31.
Figure 32 illustrates the use of VREF to provide low impedance
termination into VS/2. In addition, a way to negate the 30 mV
input offset is with external resistor values; for example, using a
1.8 V CMOS with long traces to provide far end termination.
