Programmable oscillators are basically oscillators – which work with the help of electronic components – that are designed to produce fixed, repeating pulses of limited duration. They offer a range of different parameters that allow users to adjust or "program" the timing of oscillations produced. The most common parameter that is programmed is frequency, which is usually also the most important parameter. SIT9005ACR1H-25SI is an example of a programmable oscillator.

The SIT9005ACR1H-25SI oscillator is a special type of crystal oscillator, typically used in applications where long-term stability and low-power consumption are important. It is a surface mount CMOS device that features a wide frequency range of 2 MHz to 25 MHz and a supply voltage of 3.3V. The device is specifically designed to offer superior acoustic noise performance, making it ideal for audio-processing applications. It also has a low-current draw of less than 0.1 mA, making it suitable for battery-powered applications.

The SIT9005ACR1H-25SI oscillator features self-compensated load tuning, meaning that its frequency does not have to be programmed but instead is automatically adjusted to match the load. This ensures that the device stays within the specified frequency range and provides consistent timing pulses. Additionally, the oscillator has a phase noise performance as low as –150 dBc/Hz at 10 kHz offset, making it suitable for applications requiring high signal quality, such as synthesizers and digital radio systems.

The working principle behind the SIT9005ACR1H-25SI is based on the resonance of a quartz crystal. When an electrical signal is applied to the crystal, it vibrates at its resonant frequency, creating an oscillation that is applied to the load circuit. The crystal oscillator then adjusts the frequency of the oscillations to match the required parameters, providing a reliable source of high-precision timing pulses. This makes the SIT9005ACR1H-25SI ideal for applications where precise timing and accuracy are essential, such as in telecommunications, instrumentation, and radar.

The SIT9005ACR1H-25SI is an extremely reliable and cost-effective solution for a wide range of applications. It is specifically designed to offer superior acoustic noise performance, low-power consumption, long-term stability, and accurate timing pulses. These features make the oscillator ideal for applications in telecommunications, instrumentation, and even audio-processing.
