APPLICATION INFORMATION  
POWER SUPPLY FILTERING TECHNIQUES  
As in any high speed analog circuitry, the power supply pins  
are vulnerable to random noise. The ICS874004 provides  
separate power supplies to isolate any high switching  
noise from the outputs to the internal PLL.VDD, VDDA, and VDDO  
should be individually connected to the power supply  
plane through vias, and bypass capacitors should be  
used for each pin. To achieve optimum jitter performance,  
power supply isolation is required. Figure 1 illustrates how  
a 10resistor along with a 10µF and a .01µF bypass  
capacitor should be connected to each VDDA pin.

FIGURE 1. POWER SUPPLY FILTERING  
WIRING THE DIFFERENTIAL INPUT TO ACCEPT SINGLE ENDED LEVELS  
Figure 2 shows how the differential input can be wired to accept of R1 and R2 might need to be adjusted to position theV_REF in  
single ended levels. The reference voltage V_REF = VDD/2 is the center of the input voltage swing. For example, if the input  
generated by the bias resistors R1, R2 and C1.This bias circuit clock swing is only 2.5V andVDD = 3.3V,V_REF should be 1.25V  
should be located as close as possible to the input pin.The ratio and R2/R1 = 0.609.
