12.0 POWER SUPPLY SUGGESTION
1.A solid ground plane should be placed around the clock device. Ground connections should be tied
2.C21,C22,C31,C36 are decoupling capacitors ( 0.1µF surface mount, low ESR, ceramic capacitors.)
3.C1 and C2 are supply filtering capacitors for low frequency power supply noise. A 22µF (or 10µF)
4.Use of Ferrite Bead? (FB) are recommended to further reduce the power supply noise.
5.The power supply race to the Vdd pins must be thick enough so that voltage drops across the trace
(3.3V)
Vdd
to this main ground plane as short as possible. No cuts should be made in the ground plane
around the device.
They should be placed as possible as the Vdd pin and the ground via.
tantalum capacitor is recommended.
resistance is negligible.
