CWX813-020.0M Application Field and Working Principle

Introduction to Oscillators

Oscillators are devices that generate electrical signals. Oscillators are used as a timing reference for programmable logic, for precision analog signals such as those used in communications systems, and for synchronizing digital systems. Oscillators produce a continuous output signal that has a regular frequency or waveform which is used to control the frequency, phase, and other aspects of analog and digital circuits.

Types of Oscillators

Oscillators can be classified into two main categories – linear and digital. Linear Oscillators are used for producing analog signals and digital Oscillators are used for generating digital signals. Linear oscillators can be further divided into high-amplitude oscillators, low-amplitude oscillators, voltage-controlled oscillators, and frequency-modulated oscillators. Digital Oscillators are also divided into two categories; analog-to-digital oscillators and digital-to-digital oscillators.

CWX813-020.0M Application Field and Working Principle

CWX813-020.0M is a frequency-modulated linear oscillator which is designed for use in precision analog and digital systems. It is a highly stable, low-amplitude oscillator with a frequency range of 20MHz to 200MHz. This makes it suitable for use in a variety of applications such as frequency synthesis, time-division multiplexing, and telemetry.The CWX813-020.0M uses a silicone oscillator that is controlled by a phase-locked loop circuit to achieve a frequency accuracy of ±1Hz across the entire frequency range. The integrated circuit (IC) contains a frequency synthesizer that modifies the oscillator signal to generate output frequencies which are accurate to within ±1Hz.The phase-locked loop circuit ensures that the frequency of the output signal is locked to a reference signal, thereby eliminating any slight frequency drifts which can occur due to environmental or temperature changes. This ensures that the signal remains as accurately timed as possible.The oscillator also features an output enable pin which allows the user to enable or disable the oscillator with ease. This feature is especially useful in applications where the oscillator needs to be switched on or off at regular intervals.

Conclusion

CWX813-020.0M is an advanced linear oscillator which is designed for use in precision analog and digital systems. It utilizes a frequency-modulated oscillator in conjunction with a phase-locked loop circuit to provide an accurately tuned output signal. The oscillator also features an output enable pin which allows the user to enable or disable the oscillator with ease. This makes the CWX813-020.0M an ideal choice for a wide range of applications in the industry.
