Oscillators

Oscillators are electronic components and circuits used to generate electrical signals with a specific frequency, and are a key part of many electronic systems and applications. One example of an oscillator device is the Dialog Semiconductor 530FA270M000DG, a customized silicon oscillator for use in high-accuracy timing applications.

Application Field of Dialog Semiconductor 530FA270M000DG

The Dialog Semiconductor 530FA270M000DG is specifically designed for use as an oscillator component in devices that require precision timekeeping or frequency output accuracy. Its high accuracy is notable, with tolerance kept within a few ppm per device. Application fields for the 530FA270M000DG include radio frequency (RF) circuits, satellite communications equipment, test equipment, and navigation systems.

Working Principle of Dialog Semiconductor 530FA270M000DG

The 530FA270M000DG produces a reference frequency by employing an oscillator (resonator) circuit. The output of the resonator is then buffered and amplified to create an output signal with a specific frequency. The output signal is highly stable due to the careful selection of the frequencies produced by the oscillator component. This signal is then further stabilized by an internal digital divider and a post-divider synchronization circuit.

The digital divider utilizes a frequency counter to count the number of clocks of the incoming signal and then divides the frequency by the desired division ratio. This provides a low noise and low jitter output frequency. To enhance jitter reduction and stable operation, external loop filter components can be connected to the output signal. As a result, the 530FA270M000DG provides output signals with a frequency error tolerance as low as a few parts-per-million (ppm), which is suitable for use in many precision timing applications.
