The word “oscillators” usually refers to devices used to help stabilize frequency. With the growth of the consumer electronic industry, oscillators have become more commonplace. Developers have been working hard to create new oscillators designed to provide more stabilization and lower production costs.
Over the years the precision crystal oscillator has become more important. Even though less precise oscillators have been created to with cheaper materials, crystal is still preferred. This type of oscillator provides a level of stability that few oscillators can emulate.
The quality of the frequency depends largely on the quality of the crystal. A precision crystal oscillator is usually cut in a shape designed to provide stable frequencies throughout the year. Tuning for crystals are the most popular since their resonances provide the best frequency. The only problem associated with precision crystal oscillators are the negative effects that occur because of low temperatures. In order to get the best results, crystals should remain at room temperature.
There are many uses for the crystal oscillator, with the most common being clocks. The frequency provided helps keep a clock’s time steady and stable throughout the year. They are also used for audio output and radio receivers. When using a crystal oscillator for a clock, it’s important to remember that going above or below room temperature will affect the time of the clock. Clocks lose between two and eight minutes each year because of crystal temperature changes.
Even though crystal oscillators are used for radios, the variable frequency oscillator is highly recommended. A variable frequency oscillator will control the frequency of any radio receiver transmitter that uses the superheterdyne principle. The most common types of variable frequency oscillator signals are analog and digital.
Core Electronics has both types of oscillators available for your use. All oscillators are created using only new materials. Crystal oscillators are tested to help address and fix some of the problems caused by exposure to heat and cold.
