OSCILLATOR DRIVER
FOR CRYSTAL OSCILLATOR OR CERAMIC RESONATOR
SCES469C–AUGUST 2003–REVISED JULY 2005
After the selection of proper component values, the oscillator circuit should be tested, using these components,
to ensure that the oscillator circuit shows required performance over the recommended operating conditions.
Without a crystal, the oscillator circuit should not oscillate. To check this, the crystal can be replaced by its
equivalent parallel-resonant resistance.
When the power-supply voltage drops, the closed-loop gain of the oscillator circuit reduces. Ensure that the
circuit oscillates at the appropriate frequency at the lowest V
CC
and highest V
CC
.
Ensure that the duty cycle, start-up time, and frequency drift over time is within the system requirements.
