Oscillators

An oscillator is an electronic device that generates a continuous output signal without requiring an input signal. A typical oscillator circuit consists of an amplifier, an oscillator control element, a frequency-determining network, a feedback loop, and a power source. A power source provides a necessary voltage level to the oscillator control element, which is then responsible for initiating the oscillation cycle. This oscillation cycle generates an alternating current signal, which is typically at a constant frequency.

DOCAT020F-020.0M Application Field and Working Principle

DOCAT020F-020.0M is a type of oscillator that is specifically designed to generate high frequency signals. It is widely used in automotive and industrial applications such as automotive infotainment systems, navigation systems, and vehicle data logs. The device operates on a voltage range of 5V to 36V and has low jitter performance, making it suitable for a wide range of applications. The oscillator is available in the TO-263, SOT-363, SOT-666, and DIP8 package.

The working principle of the DOCAT020F-020.0M is based on the relaxation oscillator concept. The oscillator comprises of an amplifier, an oscillator control element, and a frequency-determining network. The amplifier provides the necessary amplification and converts the DC power into an AC signal. The oscillator control element is responsible for initiating the oscillation cycle and the frequency-determining network determines the frequency of the signal. The feedback loop enables the oscillator to provide a stable output signal.

The oscillator has three main modes of operation: free-running, manual-reset, and auto-reset. In the free-running mode, the control element initiates the oscillation cycle when the power is applied to the oscillator. In the manual reset mode, the oscillator can be reset by an external signal. In the auto-reset mode, the oscillator will automatically reset itself once the power is cycled.

The DOCAT020F-020.0M has a wide operating temperature range of -40 to +125 degrees Celsius, making it suitable for numerous automotive and industrial applications. Its high frequency performance and low jitter, combined with its high temperature tolerance, make it an ideal choice for high performance applications such as automotive infotainment systems, navigation systems and vehicle data logs.
