OSCILLATOR
The oscillator circuit of the uPSD321X Devices is
a single stage inverting amplifier in a Pierce oscil-
lator configuration (see Figure 18). The circuitry
between XTAL1 and XTAL2 is basically an invert-
er biased to the transfer point. Either a crystal or
ceramic resonator can be used as the feedback el-
ement 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.
