1.4.2.2 Ceramic Resonator Oscillator
To reduce cost, use a ceramic resonator instead of the crystal. The circuits shown in
Figure 1-6
and
Figure 1-7
show ceramic resonator 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.
Mount the resonator and components as close as possible to the pins for startup stabilization and to
minimize output distortion. An internal startup resistor of approximately 2 M
is provided between OSC1
and OSC2 as a programmable mask option.
