Note:
*
Recommended crystal oscillator CI values:
CI
≤
120Ω (For a 4.5 MHz crystal)
CI
≤
70Ω (For a 7.2 MHz crystal)
However, since the oscillator circuit characteristics depend on the printed circuit board and component values actually used, we recommend
requesting a circuit evaluation from the manufacturer of the crystal used.
<Sample Ocsillator Circuit>
Crystal oscillator: HC-49/U (manufactured by Kinseki, Ltd.), CL = 12 pF
C1 = C2 = 15 pF
The circuit constants for the crystal oscillator circuit depend on the crystal used, the printed circuit board pattern, and other items. Therefore we
recommend consulting with the manufacturer of the crystal for evaluation and reliability.
