Programmable Oscillators

Many devices and systems rely on oscillators to provide the clock signals they need to operate. Oscillators produce signals with a peak frequency according to the requirements of the system. Because different systems require different peak frequencies, Programmable Oscillators were made to provide versatility to engineers who design systems. Programmable Oscillators allow engineers to change the peak frequency of the oscillator to whatever they need, a feature that is not offered with most regular oscillators.

In particular, the SIT9002AI-18H25DK Programmable Oscillator is designed to offer the features and flexibility engineers require. This type of oscillator provides a peak frequency from 0 to 50MHz and offers a small size, excellent frequency stability, and high reliability for their application field. It also provides accurate frequency control, low power consumption, and excellent cost performance. The SIT9002AI-18H25DK also provides an output low noise input buffer and a low jitter output buffer, both of which are essential for providing consistent performance.

The working principle of the SIT9002AI-18H25DK Programmable Oscillator is based on digital pulse-width modulation. This technology uses a digitally sourced linear voltage-controlled oscillator (VCO) to achieve the desired frequency. The linear VCO is feeding into a pulse width modulator, which is a two-state circuit consisting of two digital switches. The width of the output pulse is determined by the duty cycle, or ratio of the time the switch is in the "on" state and the time it is in the "off" state. The VCO determines the frequency of the oscillator, while the duty cycle is used to adjust the amplitude of the output signal.

The modulator is then fed into a low pass filter, which is a component that is meant to filter out high frequency signals. The low pass filter will remove any noise that is present in the signal, and then the clean signal is then sent to the output. The oscillator is controlled by an externally supplied voltage, which is used to adjust the frequency of the oscillator. The output frequency can be changed based on the change in the voltage, allowing engineers to easily adjust the output frequency to the desired value.

The SIT9002AI-18H25DK Programmable Oscillator provides an excellent solution for engineers who require a high quality, reliable oscillator for their application field. By offering a high frequency range, reduced size, accurate frequency control, and low power consumption, the SIT9002AI-18H25DK Programmable Oscillator offers a cost-effective solution that is designed to meet engineers’ most demanding applications.
