Oscillators

Oscillators are circuits that generate and regulate frequency-dependent electronic signals. These signals are typically sinusoidal in nature, meaning they contain a steady repeating peak and valley, like the alternating wave form of a sine wave. Oscillators are an important component of radio technology, acting as a frequency generator that can be tuned to produce signals. Examples of oscillator applications include digital circuits, clock and data recovery circuits, timing circuits, logic and microprocessor systems, filter networks and more. This article will focus specifically on the ABDFVCTCXO-20.000MHz-E-2-T5 oscillator and discuss its application field and working principle.

Application Field of the ABDFVCTCXO-20.000MHz-E-2-T5

The ABDFVCTCXO-20.000MHz-E-2-T5 oscillator is a surface mount voltage-controlled crystal oscillator (VCXO). Due to its small size, the device is suitable for use in communications systems, such as Frequency-Domain Multiplexing (FDM) systems, Time-Division Multiplexing (TDM) systems, Orthogonal Frequency Division Multiplexing (OFDM) systems, microwave systems, signal and data generators, radar, military applications, and more. It can also be used in industrial systems as a frequency or time reference.

Working Principle of the ABDFVCTCXO-20.000MHz-E-2-T5

The ABDFVCTCXO-20.000MHz-E-2-T5 device is an oscillator that uses a quartz crystal to produce a signal with a frequency of 20.000 MHz. The crystal is usually referred to as a “piezoelectric crystal”; it contains a small electrical charge and is able to act like a capacitor when an electrical voltage of the correct polarity is applied. The electrical charge stimulates the crystal, causing it to vibrate at its natural resonant frequency, which is set in the oscillator’s configuration during the manufacturing process. The signal generated by the crystal oscillator is a clean and stable sinusoidal waveform (sine wave), which can be used to control the frequency of other circuits. It is also possible to adjust the frequency of the oscillator by supplying a control voltage to the device, hence the term “voltage controlled crystal oscillator” (VCXO).

The ABDFVCTCXO-20.000MHz-E-2-T5 oscillator is very reliable; it can be used in a wide range of temperatures and is not affected by environmental fluctuations or vibration. Additionally, the device offers excellent noise levels and can offer the tightest oscillator stabilities available. It is therefore an ideal device for a variety of applications where high-performance oscillators are required.
