Hardware Design Considerations
PLL Power Filtering
3.1
To further enhance noise isolation, an external filter is strongly recommended for PLL analog VDD pins.The filter shown in Figure 2 should be connected between the board VDD and the PLLVDD pins.The resistor and capacitors should be placed as close
