Oscillators

Oscillators are electronic circuits which produce a repeating and periodic waveform signal, usually a sine wave, square wave or triangle wave. Oscillators are widely used for frequency generation and control, signal generation, pulse trainers, pulse modulators, and data sources. Most oscillators consist of an amplifier and a frequency determining element, typically a tuned circuit, resistor-capacitor (RC) network, or crystal.

The 550FD120M000DGR Oscillator is a precision dual timer oscillator designed to meet the requirements of a range of applications. The oscillator uses a dual timing element to provide a constant output frequency over a range of operating temperatures and supply voltages. Its outputs have an amplitude of 2.5V and are stable over a temperature range of -10°C to 70°C.

Application Field

The 550FD120M000DGR oscillator has a wide range of applications due to its precision and stability. It is suitable for applications such as microprocessors, network equipment, embedded controllers, audio systems, modems, motor controllers, and time bases. It can also be used for communication systems, clock generators, timers, and multi-phase motors. The dual timer elements allow the oscillator to be used for phase locked loops, frequency synthesizers, and clock distribution.

Working Principle

The 550FD120M000DGR oscillator is based on a dual timer oscillator which uses two timing elements to provide constant output frequencies over a range of operating temperatures and supply voltages. The components that make up the oscillator include a crystal oscillator, an amplifier, and a reference timing element. The crystal oscillator is used to generate the desired frequency, while the amplifier is used to boost the output of the crystal oscillator to the required level and to provide isolation against both mechanical and electrical disturbances. The reference timing element is used to set the timing and to ensure accuracy.

The crystal oscillator works by converting mechanical energy into electrical energy through the piezoelectric effect. When the crystal is excited, its oscillation frequency is determined by the size and type of crystal, the operating temperature, and the applied voltage. The amplifier conditions the signal from the crystal to the necessary level and provides isolation against any mechanical and electrical disturbances. The reference timing element is used to ensure the accuracy of the timing, as the crystal oscillator is affected by factors such as temperature and voltage. It also provides a stable reference point when the oscillator is used for frequency synthesis.

The 550FD120M000DGR oscillator is capable of being adjusted to different frequencies and is suitable for precision timing and frequency signal generation applications requiring high stability and accuracy. It is also capable of providing stable outputs over a wide range of temperatures and voltages, and is therefore suitable for telecommunications and military applications.
