Working Principle of 550CD000149DGR Oscillator

The 550CD000149DGR oscillator is a specialized type of quartz crystal oscillator. It consists of a quartz crystal and a few discrete components, usually including a capacitance, inductance, and buffer amplifier. The quartz crystal is the oscillator’s active component, which, when energized, vibrates at its resonant frequency. The buffer amplifier amplifies the oscillator’s output signal and reduces circuit loading, which helps maintain frequency stability even in the presence of temperature drift and variations in load current.

This oscillator utilizes a unique design with an integrated temperature compensating circuit to improve frequency stability over a wide operating temperature range. The temperature compensating circuit includes a temperature sensor and an RC circuit. The temperature sensor detects any changes in ambient temperature and feeds this information to the RC circuit which adjusts the capacitance value of the oscillator’s tank circuit to compensate for temperature variations. This ensures that the output signal remains stable over a wide temperature range.
