Programmable oscillators are electrical components that provide an adjustable frequency, or timing oscillations in an electronic circuit or system. They are used to generate a series of pulses or a signal with a consistent period and frequency. One of the most popular programmable oscillators is the SIT9005ACR2G-25SD. In this article, we will take a look at the application fields and working principle of this oscillator.

The SIT9005ACR2G-25SD is an adjustable phased-locked-loop (PLL) type oscillator. It features a wide range of selectable frequency (from 10MHz to 150MHz) and adjustable duty-cycle (from 30% to 70%). It is ideal for applications where high frequency stability and accuracy are essential, such as GPS modules, instrumentation, digital audio, Bluetooth devices, etc. With its small size and high performance, it is ideal for portable application.

The SIT9005ACR2G-25SD consists of a frequency setting network, voltage-controlled oscillator, pull-up circuit and a phase-locked loop circuit. The frequency setting network helps the user fine-tune the output frequency by changing the internal resistance. The voltage-controlled oscillator is the heart of the oscillator and is able to generate a stable signal with an adjustable frequency range of 10MHz to 150MHz. The pull-up circuit adjusts the duty cycle of the output signal, while the phase-locked loop circuit helps maintain a consistent frequency. The output frequency is determined by the ratio between the internal capacitance and external capacitance. In addition, the device also features thermal stability and low ripple output.

In the field of GPS systems, the SIT9005ACR2G-25SD is used to generate a precise reference frequency which is needed for accurately positioning. It is ideal for generating precise frequencies to serve as a reference for data transmission and sampling. It is also suitable for automotive applications, such as for controlling frequency for power supply and sensors. In digital audio systems, the SIT9005ACR2G-25SD is used to generate precise frequencies for audio sampling and transmission. It is used in digital audio streamers, CD players, receivers, and other digital audio devices.

The SIT9005ACR2G-25SD is one of the most popular programmable oscillators due to its wide range of frequency selection, adjustable duty cycle and precise accuracy. It is ideal for many applications such as GPS modules, instrumentation, digital audio, Bluetooth devices, automotive systems and many more. With its wide range of features, it can satisfy the needs of most high-precision applications.
