Working Principle

The MX574BNR805M664-TR is an oscillator based on a quartz crystal device. A quartz crystal oscillator is a type of electrical circuit that uses the mechanical resonance of a quartz crystal to generate an electrical signal with a precise frequency. This frequency is determined by the characteristics of the crystal, including its size, shape, and thickness. The crystal oscillator uses a quartz crystal to create a continuous oscillating electrical signal, which is then amplified and filtered to produce a pure sine wave with a specific frequency.

The oscillator consists of several components, including a quartz crystal resonator, an amplifier, and a filter. The quartz crystal resonator is made of two pieces of quartz crystal that vibrate at a predetermined frequency when subjected to an alternating current. The amplifier is used to amplify the small electrical signal created by the quartz crystal resonator so that it has enough power to drive other circuits. Finally, a filter is used to remove any unwanted noise or harmonics from the amplified signal.

The frequency of the oscillator is determined by the resonant frequency of the quartz crystal resonator. The resonant frequency of the quartz crystal is determined by its physical characteristics, such as size, shape, and thickness. The frequency can be changed by changing one of these characteristics, or by a voltage-controlled oscillator (VCO) circuit.
