Working Principle

SG7050CCN oscillators use a piezoelectric crystal as the frequency-determining element. The crystal vibrates at a specific frequency when a certain voltage is applied to it. The frequency of oscillation depends on the specific characteristics of the crystal. This natural frequency is greatly affected by external factors, such as temperature and atmospheric pressure. To overcome this problem, SG7050CCN oscillators have a built-in voltage controlled oscillator (VCO) circuit which can compensate for any changes in the frequency of the crystal caused by external factors.

The SG7050CCN oscillator also has two other main components – a precision frequency divider and a temperature-compensated amplifier. The frequency divider divides the frequency of the crystal input signal by a certain number, while the amplifier amplifies the signal to an appropriate level. The VCO circuit is then used to adjust the frequency to keep it constant.

SG7050CCN oscillators therefore combine the precision of a crystal oscillator with the flexibility of a VCO to provide a very stable and accurate frequency source.
