Application

The AX7DCF1-1216.5000T quartz crystal oscillator is widely used in a variety of electronic applications, including military communications, aerospace, fixed-frequency mobile communication systems, and other handheld devices. It is also suitable for radio receivers, television receivers, computer systems, industrial equipment, and medical equipment.

Construction

The AX7DCF1-1216.5000T quartz crystal oscillator is constructed using a quartz crystal resonator, an electronic circuit, and an oscillation output buffer amplifier. The resonator consists of a quartz crystal mounted between the leads and connected to the input terminals. The crystal acts as an oscillator, oscillating at a frequency dictated by its physical properties. The tank circuit, consisting of two capacitors and an inductor, is connected to the crystal and helps to stabilize the frequency output of the oscillator. The output buffer amplifier is connected to the tank circuit and amplifies the signal to produce the oscillation output.

Operation

Quartz crystals are naturally piezoelectric. Piezoelectricity is the generation of a voltage when a crystal is subjected to mechanical stress. Quartz crystals are cut in a precise geometry that causes them to vibrate when a voltage is applied across them. This is known as electrostriction. When the quartz crystal is exposed to a voltage, it begins to vibrate at its resonant frequency. The vibration produces a voltage across the quartz crystal that is converted to a frequency and amplified by the output buffer amplifier to produce a frequency signal.

Advantages

Quartz crystal oscillators offer many advantages when compared to other types of oscillators, including higher frequency accuracy, greater temperature stability, and low power consumption. Furthermore, quartz crystal oscillators can operate over a wide range of temperatures and frequencies, making them suitable for many applications.

Conclusion

The AX7DCF1-1216.5000T quartz crystal oscillator is ideal for a range of electronic applications, including military communications, aerospace, fixed-frequency mobile communication systems, and other handheld devices. Its construction and operation make it capable of high frequency accuracy, superior temperature stability, and low power consumption.
