Working Principle

The ASTMHTA-120.000MHz-AK-E oscillator is a type of crystal oscillator. It consists of a crystal resonator, an amplifier, a voltage-controlled oscillator (VCO), and a filter circuit. The crystal resonator has an inherent frequency of oscillation when excited. This frequency is determined by its characteristics, such as dimensions, materials, and cut angles. The amplitude of the oscillations is determined by the size of the crystal and is determined by its specified quality factor.The amplifier drives the crystal resonator to maintain an excessive voltage across the crystal resonator and ensure an optimal frequency stability over a wide range of temperatures. The VCO is a chip which provides a variable frequency output that can be adjusted over a wide range of frequencies. The filter circuit is usually an LC low-pass filter that is used to filter out any unwanted harmonic components from the VCO signal, and to ensure stability of the oscillator operation. The output frequency of the ASTMHTA-120.000MHz-AK-E oscillator is determined by the crystal resonator, and the frequency stability over a wide temperature range is guaranteed by the amplifier and VCO circuit.
