General Description
1.5.2.2 Ceramic Resonator Oscillator
Technical Data
To reduce cost, use a ceramic resonator instead of the crystal. The
circuits shown in
circuits. Follow the resonator manufacturer’s recommendations, as the
resonator parameters determine the external component values
required for maximum stability and reliable starting. The load
capacitance values used in the oscillator circuit design should include all
stray capacitances.
