μPSD325X DEVICES
OSCILLATOR
The oscillator circuit of the
μPSD325X devices is a
single stage inverting amplifier in a Pierce oscilla-
tor configuration. The circuitry between XTAL1
and XTAL2 is basically an inverter biased to the
transfer point. Either a crystal or ceramic resonator
can be used as the feedback element 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 μPSD325X devices ex-
ternally, XTAL1 is driven from an external source
and XTAL2 left open-circuit.

SUPERVISORY
There are four ways to invoke a reset and initialize
the μPSD325X devices.
I
Via the external RESET pin
I
Via the internal LVR Block.
I
Via USB bus reset signaling.
I
Via Watch Dog timer
The RESET mechanism is illustrated in Figure 20.
