Programmable Oscillators

Programmable oscillators are electronic components used to generate sinusoidal oscillations at times of varying frequency and fixed or adjustable amplitude. Examples include quartz crystal oscillators, voltage-controlled oscillators (VCOs), and resonant-ring oscillators. Programmable oscillators are used either as clock generators or as signal sources in test and measurement equipment, wireless data communication systems, medical instrumentation, and other electronic systems.

The SIT1602ACR1-30E is one type of programmable oscillator. It is a miniature two-row surface-mountable oscillator with minimal power consumption, wide frequency range from 1.2 MHz to 30 MHz, and low noise performance. It offers several features including selectable load capacitance, output level, frequency type, and modulation type. The SIT1602ACR1-30E is available in two package types (Tsmall and Tlarge), with four different operating temperature ranges from -40°C to +85°C.

Application Field of SIT1602ACR1-30E

The design is compliant with RoHS standards, making it suitable for various applications in electronic products.

Working Principle of SIT1602ACR1-30E

The SIT1602ACR1-30E programmable oscillator works on the simple principle of a vibrating mechanical system that is electrically coupled to an external circuit. The mechanical system is made up of a quartz crystal resonator, which vibrates at a certain fixed frequency when an external electrical signal is applied. An electrical signal with a frequency near the resonant frequency of the crystal will cause the crystal to resonate at that frequency. The output frequency is then amplified and buffered to provide the output signal.

The frequency of the oscillator can be easily adjusted by changing the load capacitance across the crystal. This is done by selecting the external capacitors connected to the crystal, since the capacitance will determine the frequency of oscillation. Additionally, the oscillator\'s amplitude and frequency stability can be enhanced using the temperature compensation voltage provided by the SIT1602ACR1-30E.
