OSCILLATOR
The oscillator circuit of the uPSD321x Devices is a
single stage inverting amplifier in a Pierce oscilla-
tor configuration (see Figure
19
). The circuitry be-
tween XTAL1 and XTAL2 is basically an inverter
biased to the transfer point. Either a crystal or ce-
ramic resonator can be used as the feedback ele-
ment to complete the oscillator circuit. Both are
operated in parallel resonance.
XTAL1 is the high gain amplifier input, and XTAL2
is the output. To drive the uPSD321x Devices ex-
ternally, XTAL1 is driven from an external source
and XTAL2 left open-circuit.
