Specifications

Note: * Recommended crystal oscillator CI values:

CI

≤ 120Ω (For a 4.5 MHz crystal)

CI

≤ 70Ω (For a 7.2 MHz crystal)

<Sample Oscillator 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.
