Introduction

Before discussing the application field and working principle of an ASTMHTE-12.000MHZ-AC-E-T3 oscillator, it is important to first understand what an oscillator is. An oscillator is a circuit or device that generates an output signal at a fixed frequency or creates a regularly-recurring waveform with specific electrical characteristics. Common types of oscillators are frequency-multivibrators, ring oscillators, digital oscillators, and atomic oscillators. Oscillators are used for many different applications, such as radio transmitters, receivers, and timekeeping systems.

Application Field and Working Principle

The ASTMHTE-12.000MHZ-AC-E-T3 oscillator is a low-voltage, high-frequency, crystal-controlled device. It is designed to provide a highly-stable signal with a low noise floor and a high signal-to-noise ratio. The device is ideal for use in applications such as frequency synthesis, video distribution, spectrometers, and medical and communications systems. One of the advantages of this oscillator is that it can be operated with low-power consumption and minimal component count.The ASTMHTE-12.000MHZ-AC-E-T3 oscillator uses a crystal as its main frequency reference. The oscillator oscillates at the frequency of the crystal and produces a stable output signal at the frequency of the crystal. The oscillator can be adjusted by changing the supply voltage or by using external components, such as capacitors or resistors, to tune the oscillator\'s frequency.Theoscillatorusesanintegratedcircuit(IC)toprovideasecondarysourceofstabilitybyeitherlockingtothecrystal\'sfrequency,ortomaximizethegainoftheoscillator.Thegainoftheoscillatoriscontrolledbythelengthofthetime-delayloopthattheoscillatoruses.Astableoscillatoroperationcanbeprovidedwithalargerloop.The output signal from the ASTMHTE-12.000MHZ-AC-E-T3 oscillator is highly-reliable due to its low phase noise and excellent long-term stability.
