Tuning the Oscillator Circuit
Since Microchip devices have wide operating ranges (frequency, voltage, and temperature;
depending on the part and version ordered) and external components (crystals, capacitors,...),
of varying quality and manufacture; validation of operation needs to be performed to ensure that
the component selection will comply with the requirements of the application.
There are many factors that go into the selection and arrangement of these external components.
These factors include:
• amplifier gain
• desired frequency
• resonant frequency(s) of the crystal
• temperature of operation
• supply voltage range
• start-up time
• stability
• crystal life
• power consumption
• simplification of the circuit
• use of standard components
• combination which results in fewest components
