OSCILLATORS are very useful for countless applications and their existence is essential for the modern technology. The DSC1001BE2-125.0000 is an example of an oscillator that can be used for many different applications.

A domain in which this device can be used is to stabilise clock transitions in digital circuits. The oscillator\'s signal can act as the timebase necessary to synchronise data transfers or to manage addresses. This role in digital design is fundamental and this device is especially qualified for this purpose. It is a highly accurate oscillator, with a frequency stability of 150 ppm, and a base frequency of 125.0000 Hz.

Noise is a real issue in digital systems and this oscillator has a signal to noise ratio of 105 dB. This indicates that small signal variations due to noise will not influence the transitions in the system. Additionally, this oscillator has a typical power supply rejection of 85 dB, meaning that the oscillator\'s frequency base is very stable even when voltage variations occur in the input circuit.

The working principle of this oscillator is introduced and explained with an example. A quartz crystal, made of silica quartz, forms a part of the design. When a static voltage is applied to the crystal it creates an electro-mechanical force that makes the crystal vibrate at a certain frequency. This frequency is the base frequency of the oscillator. The crystal is connected to an amplifier circuit. This circuit has an AC and a DC feedback system which sustains the amplification process and ensures that the oscillator signals maintain a constant frequency. The obtained signal then can be applied to a load.

An oscillator is a closed loop system where the output of the circuit is the same as the input but at the oscillation frequency. It is a linear structure which means that it does not require complex calculations to determine the output frequency. Depending on the frequency desired, different types of oscillators can be constructed.

Many different applications use oscillators in order to stabilize the frequency of a signal. In a digital circuit, the oscillator can serve to maintain the speed of data transfer by acting as a timebase. In a radio receiver, the oscillator can serve as a selectivity tool, allowing only frequencies near the desired frequency to pass.

The DSC1001BE2-125.0000 is a high quality oscillator designed for applications that require an accurate, stable signal with minimal drift. Its structure makes it suitable for digital circuits, especially with regard to its high power supply rejection. When combined with a crystal, it has the potential to become the cornerstone of many digital systems.
