All decoupling capacitors should connect to a large area low impedance ground plane through a via or short trace to minimize inductance. Optionally a small ferrite bead in series with the supply pin.

Separate ferrites are useful, not only for EMI suppression, but also for their series DC resistance which limits the inrush current during a hot plug event.

For large packages, placing decoupling capacitors on the opposite side of the board may be the best way of
AN0046: USB Hardware Design Guidelines
www.silabs.com• Use a ferrite bead for VBUS. Place near receptacle. • Use a switch that can shut off VBUS if current exceeds 500 mA. • Provide at least 96 uF decoupling capacitance on VBUS. Place near USB receptacle. • Terminate D+ and D- with 15 ohm serial resistors. Place near EFM32. • Use an ESD protection device. Place near USB receptacle.

V e h –T REF+ pin can be connected to VDDA through a resistor. • For the voltage regulator configuration, there is specific BYPASS_REG pin (not available on all packages) that should be connected either to V SS or VDD to activate or deactivate the voltage regulator specific.
