Oscillators

Oscillators are circuits or components that produce and/or maintain a periodic, repetitive sine wave or other electrical waveform at a specific frequency of operation. The most common type of oscillator is the electronic oscillator, which converts electrical energy to mechanical energy and back again, and oscillates at a chosen frequency.

One of the oscillators family is the 520T15HT38M4000 oscillator. It as a miniaturized high-frequency voltage-controlled crystal oscillator (VCXO) module that operates on the full frequency range of 25MHz - 4000MHz. It has high performance features including tight frequency stability over temperature and power supply voltage.

Application Field

The 520T15HT38M4000 oscillator is very suitable for applications with challenging requirements such as ultra-fast clocks, data and DO-160 environmental testing of avionics systems. It is also great for high performance instrumentation, radar, telecom systems, test & measurement, military communications, and other applications where high frequency, frequency stability and high performance are required.

Working Principle

At the most fundamental level, an oscillator works by oscillating a voltage difference between two opposing electrodes called a “simplified crystal” or “dielectric”. This voltage difference is known as a “threshold voltage”. When this voltage threshold is reached, an oscillation occurs in which an electric field is created within the second electrode. The field is reflected back off the electrodes and through the original crystal, allowing for an oscillating voltage.

The 520T15HT38M4000 oscillator takes advantage of this oscillation by using an external quartz crystal. All of the components of the oscillator work together to maintain the frequency of the crystal oscillator within a predetermined range. This includes such components as a DC power supply, a divider circuit, a multiplier circuit, and a voltage regulation circuit. All of these components work together to ensure that the output frequency will remain unchanged while the temperature, voltage, and other parameters vary.

The 520T15HT38M4000 oscillator also contains additional features such as a phase-lock loop (PLL) and other techniques to further stabilize the output frequency, ensuring consistent operation over temperature and other environmental conditions. With these features combined, the 520T15HT38M4000 is an ideal choice for applications requiring high accuracy and precision.

In summary, the 520T15HT38M4000 oscillator is a miniaturized, high-frequency voltage-controlled crystal oscillator module operating on the full frequency range of 25MHz - 4000MHz. It has a great performance over temperature, power supply voltage, and other environmental circumstances, making it suitable for applications such as ultra-fast clocks, instrumentation, and military communications, etc.
