Oscillators

Oscillators are a type of circuit that produces periodic signals of a specific frequency and amplitude. They are used in a wide range of applications, from controlling clock cycles in microprocessors to radio transmitters and receivers. One type of oscillator, the DSC1121CM1-012.2880T, is a temperature compensated Oscillator (TCO) which contains both a temperature sensor and a temperature compensation system.

The DSC1121CM1-012.2880T oscillator is designed for applications where high accuracy and stability are required. It offers long-term stability (<2ppm in 10 years at +25°C) and reliability. This is due to its integrated temperature compensation system which provides frequency drift compensation for temperatures from -40°C to +85°C. The output frequency of the oscillator also remains highly stable over its entire operating temperature range.

The working principle of the DSC1121CM1-012.2880T oscillator is simple. It consists of two main parts, the oscillator circuit and the temperature compensation circuit. The oscillator circuit contains an oscillator which is driven by an external voltage. This oscillator produces a square wave signal whose frequency is determined by the external voltage. The temperature compensation circuit contains a temperature sensor which is used to detect the ambient temperature. This temperature signal is passed through a compensation algorithm which adjusts the feedback voltage to the oscillator, thus compensating for the effect of temperature on the output frequency of the oscillator.

The DSC1121CM1-012.2880T oscillator is suitable for a range of different applications where high accuracy and stability are required. These include radio receivers and transmitters, precision frequency measurements, satellite transceivers, signal generators and frequency synthesizers. Its wide operating temperature range and high stability also make it an ideal choice for high reliability applications like automotive electronics and aerospace applications.
