Working Principle

The AX7MCF3-1200.0000C oscillator operates on the principle of quartz crystal resonance. This type of oscillator utilizes the properties of quartz crystals to control the frequency of the oscillation, enabling a precise and stable frequency output. The oscillator consists of a quartz crystal, a resonator, a driver, and a voltage control. The crystal is mounted on the resonator and, when a voltage is applied to the crystal, the crystal vibrates at the driving frequency. This frequency can be controlled and adjusted by changing the applied voltage. The oscillator then generates an electric signal which is converted into the required electrical output. The voltage controlled oscillator (VCO) is used for applications where the frequency needs to be adjusted over a wide range. The VCO is made up of a transconductor, a phase/frequency detector and a loop filter. The transconductor amplifies the input signal and converts it into a control voltage that can be modulated. The phase/frequency detector measures the difference between the input and the output signals and then provides a voltage that is proportional to the difference. This voltage is then filtered and applied to the transconductor to adjust the output frequency. The AX7MCF3-1200.0000C oscillator is a highly accurate and reliable device that provides a wide range of operating frequencies and stability. It is an ideal choice for a variety of applications.
