Oscillators are devices that have the ability to generate continual electrical signals without the need for user input. Examples of oscillator devices include quartz crystal oscillators, silicon MEMS oscillators, LC oscillators, and temperature compensated crystal oscillators (TCXOs). The DSC1001DI5-005.0196T belongs to the latter group, and its application field and working principles are discussed in this article.

Application Field

The DSC1001DI5-005.0196T has built-in temperature-compensating components, allowing it to stay on frequency even when exposed to a wide temperature range. This makes the device suitable for applications such as phase-locked loops, frequency synthesizers, and clock circuit. This type of oscillator also eliminates the need for external components to maintain accuracy, making it a highly cost-effective solution.

The DSC1001DI5-005.0196T is also known for its excellent performance and reliability. For example, it has a low phase noise and low drift, making it ideal for applications that require high accuracy and stability. It also has a high frequency stability under temperature, voltage, and aging conditions. Together, these features make it a highly reliable and long-lasting solution.

Working Principle

The main component in the DSC1001DI5-005.0196T is a quartz crystal resonator. The resonator acts like an oscillator, generating a continuous signal at its natural resonant frequency. The device also contains an automatic temperature compensator (ATC) to regulate the resonator’s output frequency. This ATC is made up of two major components: an oscillator circuit formed by a transistor and a resistor; and a temperature-sensing circuit comprised of a NTC thermistor and a capacitor.

The oscillator circuit is responsible for supplying the reference frequency for the resonator. The oscillator circuit produces a signal that is fed into the resonator and acts as a reference frequency for the resonator to resonate. This means that when the crystal is subjected to any changes in temperature, the reference frequency will remain the same, ensuring that the output frequency of the resonator remains stable.

The temperature-sensing circuit is responsible for providing feedback so that the resonator’s output frequency remains stable under different temperature conditions. The thermistor is capable of detecting changes in temperature and creating an output voltage that is proportional to the temperature. This output voltage is then fed into the oscillator circuit, where it is used to adjust the reference frequency, thus compensating for the effects of the changing temperature.

In summary, the DSC1001DI5-005.0196T is a reliable and cost-effective oscillator device that is well suited for applications requiring accurate and stable performance. Thanks to its built-in temperature compensator, the device is able to stay on frequency even when exposed to wide temperature ranges, which makes it an ideal choice for a variety of applications.
