5.4.1
PLL Power Filtering
To further enhance noise isolation, an external filter is strongly recommended for PLL analog VDD pins. The filter shown in
Figure 8 should be connected between the board VDD and the PLLVDD pins. The resistor and capacitors should be placed as
close to the dedicated PLLVDD pin as possible.

5.4.2
USB Power Filtering
To minimize noise, external filters are required for each of the USB power pins. The filter shown in Figure 2 should be
connected between the board EVDD or IVDD and each of the USBVDD pins. The resistor and capacitors should be placed as
close to the dedicated USBVDD pin as possible.
