Hardware Design Considerations
3.1
Analog Power Filtering
To further enhance noise isolation, an external filter is strongly recommended for the analog VDD pins (VDD_A_PLL,
VDD_RTC). The filter shown in Figure 2 should be connected between the board IVDD and the analog pins. The resistor and
capacitors should be placed as close to the dedicated analog VDD pin as possible. The 10-Ω resistor in the given filter is required.
Do not implement the filter circuit using only capacitors. The analog power pins draw very little current. Concerns regarding
voltage loss across the 10-ohm resistor are not valid.
