Technical Data
1.6.2.2 Ceramic Resonator
Technical Data
To reduce cost, use a ceramic resonator in place of the crystal. Use the
circuit in
3-pin ceramic resonator and follow the resonator manufacturer’s
recommendations.
The external component values required for maximum stability and
reliable starting depend upon the resonator parameters. The load
capacitance values used in the oscillator circuit design should account
for all stray layout capacitances. To minimize output distortion, mount
the resonator and capacitors as close as possible to the pins.
