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 6 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 7 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.
