ECS-3963-120-AU-TR Oscillator Application Field and Working Principle

Oscillators are electronic components that create an alternating current signal at a frequency determined by the components\' internal components. The ECS-3963-120-AU-TR type of oscillator is a precision crystal oscillator designed to provide low-cost, highly stable and reliable frequency references in a wide variety of communication, computing and industrial Electronic systems.

Application field

ECS-3963-120-AU-TR oscillators can be used in a variety of communication and computer systems. In communications, they can be used as reference frequencies for modems and other digital signal processing applications, as well as for clock and data communications. In computers, they are used for memory timing, bus and peripheral clock synchronization, microprocessor clock inputs, and system clock sources. Additionally, they can be used as time keeping sources for a variety of industrial and medical applications.

Working Principle

The ECS-3963-120-AU-TR oscillator consists of an AT-Cut quartz crystal enclosed in a ceramic package. The quartz crystal can be operated in either the parallel-resonant or series-resonant modes. In the parallel resonant mode, when the applied voltage is equal to the crystal’s resonant frequency, the crystal will vibrate at maximum amplitude. In the series-resonant mode, the crystal’s resonance frequency is shifted due to a combination of the capacitance and inductance of the crystal. The crystal will continue to oscillate or ‘ring’ at a fixed frequency with a small damping factor.

ECS-3963-120-AU-TR oscillators contain an oscillator circuit that is used to provide a voltage-controlled amplification and frequency stabilization of the crystal’s output. The circuit is typically based on a quartz feedback loop that uses resistors, capacitors, and transistors to filter and regulate the output signal. It also includes a temperature control circuit that compensates for variations in the crystal’s frequency due to temperature changes.

ECS-3963-120-AU-TR oscillators offer a cost-effective solution for applications that require high precision and stability. They are highly reliable and are designed to operate over wide temperature ranges. Additionally, they consume very low power, making them ideal for embedded applications where space and power consumption are critical considerations.
