Oscillators

An oscillator is any device or circuit that vibrates or oscillates electrical signals at some predefined frequency. It is the basis for many electronic circuits and systems, and can be found in almost all electronic components. The most common type of oscillator is the resonator type, which produces a low-power electrical signal at a certain frequency.

DSC1001CE1-024.0000T Application Field and Working Principle

DSC1001CE1-024.0000T is a resonator type oscillator, self-biased with BiCMOS circuitry and used to generate a signal of a given frequency. It consists of a quartz crystal resonator without a drive circuitry, and hence has a low power consumption. Its nominal frequency is 24.0000T, although it can be adjusted in small ranges to suit the operating conditions of the device.

DCD1001CE1-024.0000T is used mainly in applications where high accuracy is required, such as frequency synchronization, digital logic, and signal processing. The oscillator utilizes two transistors to oscillate with what is known as a bi-stable oscillator circuit, which consists of two transistor stages, connected in a cross-coupled manner. The first stage forms an inverter and the second stage provides feedback.

At a very high level, the oscillator is essentially a negative feedback system. As the voltage at the input of one stage goes higher, it breaks down and the voltage at the output of the stage goes lower. This provides an overriding voltages at both stages of the oscillator, thus stabilizing the signal at the desired frequency.

The output of the oscillator is taken from the two cross-coupled transistor stages, and is then conditioned further before it is passed onto the required components. The output from this stage is almost a sinusoidal wave, with some minor discontinuities. In most cases this waveform is further conditioned, depending upon the application.

The frequency of the signal generated by DSC1001CE1-024.0000T is further affected by the temperature of the surrounding environment. This is because the frequencies of the quartz crystal used in this circuit respond to small changes in temperature. However, this problem can be partially eliminated by using a temperature-compensating capacitor connected to the quartz crystal, which can help to maintain a relatively constant frequency under various operating conditions.

The DSC1001CE1-024.0000T is an ideal oscillator for high-accuracy frequency synchronization, digital logic, and signal processing applications. It is capable of handling high frequencies and providing stable signal output making it suitable for use in a wide range of applications. It is extremely lightweight and low power consumption, making it appropriate for battery powered applications.
