Oscillators

Oscillators are devices or systems which produce a repeating output signal rather than a steady state output. An oscillator is usually classified based on the type of output and the mechanism in which the oscillations are generated. Oscillators are used in many application areas that require periodic or vibratory motion such as communication systems, robotics, motion control systems, and aerospace. One example of an oscillator is the 550PK13M5600DG.

Application Fields

The 550PK13M5600DG is a pulsed-output, low-voltage oscillator used primarily in automotive and aerospace applications. In automotive applications, the oscillator is used to control timing and provide synchronization for brakes, transmissions, engine control modules, and navigation systems. It is also used in avionics and aerospace applications, primarily to provide precise timing signals in inertial navigation systems, controller area networks (CAN) systems, and digital bus systems. The oscillator offers excellent phase noise performance, EMI reduction, and long-term stability.

Working Principle

The 550PK13M5600DG is based on a temperature-compensated oscillator (TCXO) system. The oscillator consists of a piezoelectric quartz crystal and a circuit board with associated components that allow the crystal to oscillate at a specific frequency. The frequency is determined by the size of the crystal and the capacitance of the circuit board. The oscillator produces a square wave output that is controlled by a logic signal, which adjusts the output frequency. The output signal is precise and temperature-stable, making it ideal for use in automotive and aerospace applications.

The oscillator also uses a frequency control loop (FCL) to maintain frequency accuracy. The FCL uses a temperature-compensated voltage controlled oscillator (TCVCO) to sense any change in frequency and adjust the output accordingly. This ensures that the oscillator maintains accurate frequency despite changes in temperature or ambient conditions. The FCL also helps to reduce EMI by providing an output signal that is very close to a perfect square wave.The specific data is subject to PDF, and the above content is for reference
