General Description

1.7.2.1 2-Pin Crystal Oscillator
The circuit in Figure 1-3(a) shows a typical 2-pin oscillator circuit for an
AT-cut, parallel resonant crystal. The crystal manufacturer’s
recommendations should be followed, since the crystal parameters
determine the external component values required to provide maximum
stability and reliable startup. The load capacitance values used in the
oscillator circuit design should include all stray capacitances. The crystal
and components should be mounted as close as possible to the pins for
startup stabilization and to minimize output distortion. An internal startup
resistor of approximately 2 M
Ω is provided between OSC1 and OSC2
when the crystal/ceramic resonator oscillator option is used.
