Notes: 1. Since the circuit constants change depending on the ceramic oscillator and stray capacitance of
the board, the user should consult with the ceramic oscillator manufacturer to determine the
circuit parameters.
2. Wiring among OSC

, and elements should be as short as possible, and must not cross
other wiring (see figure 18).
