lists the resistor values and supply voltages to be used in the circuit for each of the USB V
The resistor and capacitors should be placed as close to the dedicated USB V
A separate filter circuit should be included for each USB V
All traces should be as low impedance as possible, especially ground pins to the ground plane.
The filter for USB_PHYVDD to VSS should be connected to the power and ground planes, respectively, not fingers
of the planes.
In addition to keeping the filter components for the USB_PLLVDD as close as practical to the body of the processor
as previously mentioned, special care should be taken to avoid coupling switching power supply noise or digital
switching noise onto the portion of that supply between the filter and the processor.
The capacitors for C2 in the table below should be rated X5R or better due to temperature performance.
USB Power Filtering
In addition to the above filter circuitry, a 0.01 F capacitor is also recommended in parallel
with those shown.
