Oscillators

Oscillators are systems that produce outputs that repeatedly oscillate back and forth between two states. Many types of oscillators are used to generate signals with a wide range of frequencies and amplitudes. Among them, DSC6101JI2A-048.0000T is a widely used oscillator. This article introduces the application field of and working principle behind this device.

Application Field

DSC6101JI2A-048.0000T oscillator is one of the most popular Quartz Crystal oscillators. It features a low jitter, high stability, wide operating temperature range and low EMI emission. Among the many applications of quartz crystal oscillators, a major one is in electronic timer. When a quartz crystal oscillator is used as a timer, the frequency of oscillation is determined by the crystal’s cut and size. Due to its stability, DSC6101JI2A-048.0000T is often used for low-frequency timing application such as in tick-tock clocks, wristwatches, sensors and instrumentation, for instance. Occasionally, it is also used to counter-timing applications such as frequency generators.

Working Principle

The working principle behind DSC6101JI2A-048.0000T is based on quartz oscillator. It consists of a quartz crystal that is vibrating at a specific frequency when exposed to an electrical signal. When electrical energy is applied to the crystal, it vibrates at a specific frequency and generates a periodic output signal. The frequency of oscillation is determined by the geometry of the crystal and the external components. In order to achieve the desired oscillating frequency of oscillation, the oscillator is composed of two main components: the quartz crystal and the oscillator’s internal circuitry. The quartz crystal is also known as an LC tank circuit. It consists of a resonant quartz crystal mounted in a cavity which is made up of a pair of metal plates. A small capacitor is then placed across the two plates. When an electrical signal is applied to the crystal, it vibrates and generates a periodic output signal. The other component, oscillator’s internal circuitry, is composed of active and passive components such as operatin in various topologies, including Pierce and Colpitts. This circuitry works to establish the frequency of oscillations and amplifies the signal for further operations. In conclusion, DSC6101JI2A-048.0000T is one of the most popular Quartz Crystal oscillators and it is used mainly for low-frequency timing applications such as in tick-tock clocks and wristwatches. Its working principle is based on the quartz oscillator which consists of a quartz crystal and the oscillator’s internal circuitry that helps to establish the frequency of oscillation and amplify the signal for further application.
