Note) Output frequency is determined by the operation expression of frequency inputted to Xtal IN.
Output (when input 27MHz) is shown above.
Note) The BU2362FV is basically placed on the board. Capacitance(0.1
µF) need to be placed between pin1(VDD2) and pin2(Vss2), pin5(AVDD) and pin6(AVss),
pin11(DVss) and pin12(DVDD). To obtain accurate frequency, some capacitance(
µF) need to be placed nearly between pin7 and GND, pin8 and GND.
In certain condition of the board, the electrolytic capacitor may need to be placed between power supply and GND. As a measure against EMI, it is effective
to place ferrite beads on the starting point of power supplied from the board to BU2362FV, and to use selected bypass capacitor(1
Ω or less) between power
supply and GND that can reduce high frequency noise.
