CLOCK GENERATOR
The oscillator circuit is a single-stage inverting amplifier in a Pierce oscillator configuration. The circuitry between pins
XTALI and XTALO is basically an inverter biased to the transfer point. A crystal must be used as the feedback element
to complete the oscillator circuitry. It is operated in parallel resonance. XTALI is the high gain amplifier input and XTALO
is the output.
To drive the device externally XTALI is driven from an external source and XTALO is left open-circuit.
