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.

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.
