One of the most important features of any oscillator is its frequency stability, or its ability to provide a constant frequency output under varying load conditions. Some of the factors that affect the frequency stability of a TCXO Oscillator generally include: variations in temperature, variations in the load as well as changes to its power supply voltage, just to name a few. To learn more about the products, visit QVSTech.com. Frequency stability of the output signal can be improved by the proper selection of the components used for the resonant feedback circuit including the amplifier but there is a limit to the stability that can be obtained from normal tank circuits.
To obtain a very high level of oscillator stability a Quartz Crystal is generally used as the frequency determining device to produce another types of oscillator circuit known generally as a Quartz Crystal TCXO Oscillator.
TCXO Oscillators for your Project
When a voltage source is applied to a small thin piece of quartz crystal, it begins to change shape producing a characteristic known as the Piezo-electric effect. This effect is the property of a crystal by which an electrical charge produces a mechanical force by changing the shape of the crystal and vice versa, a mechanical force applied to the crystal produces an electrical charge.
Then, electric devices can be classed as Transducers as they convert energy of one kind into energy of another (electrical to mechanical or mechanical to electrical). This piezo-electric effect produces mechanical vibrations or oscillations which are used to replace the LC tank circuit in the previous TCXO oscillators.
There are many different types of crystal substances which can be used as TCXO oscillators with the most important of these for electronic circuits being the quartz minerals because of their greater mechanical strength.
The quartz crystal used in a TCXO Oscillator is a very small, thin piece or wafer of cut quartz with the two parallel surfaces to make the required electrical connections. The physical size and thickness of a piece of quartz crystal is tightly controlled since it affects the final or fundamental frequency of oscillations. The fundamental frequency is called the crystals “characteristic frequency”.
Then once cut and shaped, the crystal cannot be used at any other frequency. In other words, its size and shape determines its fundamental oscillation frequency.
The crystals characteristic is inversely proportional to its physical thickness between the two metalized surfaces.
One of the most important functions of any oscillator is its frequency stability, or its capability to provide a consistent frequency output under differing load conditions. Some of the aspects that impact the frequency stability of a TCXO Oscillator typically include: variations in temperature level, variations in the load in addition to changes to its power supply voltage, simply among others.
