Piezo-electric quartz crystals are used to define the frequency in a crystal-controlled oscillator. Quartz is a hard material that tends to oscillate mechanically at a high frequency (up to about 20 MHz) when maintained by the maintaining amplifier. The signal produced is far more stable and predictable than an L-C oscillator, especially when the crystal is placed in a dedicated oven with a controlled temperature.

What is 12MHZ crystal oscillator?
An oscillator is something that produces an output that repeats regularly. In the electronics field this will be an electrical waveform, often but not always a sine wave. The most important property of an oscillator is its frequency : the rate at which the output repeats. This is measured in Hertz (Hz for short). One Hertz is one repetition (aka cycle) per second. One MegaHertz (MHz) is one million repetitions per second. One of the problems in designing a high quality oscillator is maintaining the output frequency at the value required. One method is to control it by a quartz crystal; this is cut so that it vibrates mechanically at the design frequency, and is coupled to the electronics by the piezo-electric effect. A 12 MHz crystal oscillator is an electronic circuit, whose output frequency is controlled by a quartz crystal to repeat 12 million times per second. (Note. Oscillators don't have to be electronic. Other examples are a guitar string, a flute or a pendulum. An electronic oscillator is the only one that can be crystal controlled.)

Why crystal oscillator used for microcontrollers?
Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.

For aquartz cristal of length 0.05mcalculate the fundamental frequency of oscillation in a piezo-electric oscillator if the velocity of longitudinal waves in the crystal is 5.5 x 1000 ms?
The fundamental frequency of oscillation in a piezoelectric oscillator is given by the formula f = v/2L, where v is the velocity of longitudinal waves in the crystal and L is the length of the crystal. Plugging in the values, we get f = (5.5 x 1000)/(2 x 0.05) = 55000 Hz. So, the fundamental frequency of oscillation in the piezoelectric oscillator is 55000 Hz.
