Note) The BU2382FV is basically placed on the board.

Decoupling capacitance (0.1ÂµF) need to be placed between Pin1 (VDD2) and Pin2 (VSS2),

Pin5 (AVDD) and Pin6 (AVSS), Pin11 (DVSS) and Pin12 (DVDD).

To obtain accurate frequency, capacitance (pF) need to be placed between Pin8 (XTAL IN)

and Pin6 (AVSS). Pin7 (XTAL OUT) and Pin6 (AVSS).

Tantalum capacitance (10 to 100ÂµF), ferrite beads may need to be placed to prevent power

supply drop in certain board's case.

To reduce high frequency noise, selected bypass capacitors (<1â¦ at problem high frequency)

maybe used for power pin as close to BU2382FV as possible.
