The temperature controlled crystal oscillator is also known as TCXO or Xtal oscillator. By applying the temperature compensation with the crystal oscillator modulator, it is possible to improve the basic performance of the oscillator. These are the type of crystal oscillators used where an accurate frequency source is required within a small space. These oscillators are available at the economic costs in the market. The application of temperature compensation within the crystal oscillator module, makes it possible to considerably improve on the basic performance of the oscillator. The major players in the market of temperature controlled crystal oscillator across the globe are providing a wide range of products on the basis of their usefulness, in different variety of packages. The crystal oscillators offer a highly suitable form of oscillator, but they are affected by temperature. So there are a temperature- sensitive reactance circuits present in the oscillation loop, which compensate the frequency temperature characteristics inherent to the crystal unit. A temperature controlled crystal oscillator regulates the frequency of the oscillator to compensate for the changes that will take place due to a result of temperature change. It create a correction voltage to reduce the inherent frequency versus temperature characteristic of the crystal. Earlier the design of these oscillators included network of thermistors and resistors to create a correction voltage. These thermistor/resistor network TCXOs are still relevant and found in specific environments including satellite and other space applications where modern solid-state devices do not have the radiation hardness to survive. The TCXO’s performance limits to ±0.1 ppm. This is due several factors such as, the resonators are not perfect or the polynomial generator are non-ideal and persuades some higher order artifacts, leaving the user with residuals of ±0.1 ppm. To overcome this new methodology which uses an artificial neural network (ANN) to create the correction voltage has recently been demonstrated.
The global temperature compensated crystal oscillator market is segmented on the basis of type, application and region. On the basis of type, the temperature compensated crystal oscillator market has been segmented into indirect compensated crystal oscillator and direct compensated crystal oscillator. Based on application, the temperature compensated crystal oscillator market is divided into electronic products, wireless systems and others. The electronic products segments is expected to dominate the temperature compensated crystal oscillator market due to the application of TCXO’s in various instruments such as automatic power meters, GPS receivers, network timing and synchronization in servers, routers, hubs, and switches, telematics and other applications. The factors that are helping the companies for the growth of the market are that TCXOs are being used in most of the electronic instruments from cell phones to smart munitions and embedded applications.
