12MHz crystal oscillator

A 12MHz oscillator circuit with 2 pinouts which uses mechanical resonance of a vibrating crystal of piezoelectric material to generate an electrical signal with an accurate frequency. It has automatic amplitude control and its frequency drift is also very low due to change in temperature.
