microcontroller
SAA5290
Clock generator
The oscillator circuit of the SAA5290 is a single-stage
inverting amplifier in a Pierce oscillator configuration. The
circuitry between OSCIN and OSCOUT 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. OSCIN is the
high gain amplifier input and OSCOUT is the output. To
drive the SAA5290 externally OSCIN is driven from an
external source and OSCOUT is left open-circuit.
