Introduction to Programmable Oscillators

Programmable oscillators are electronic components that generate an alternating electrical signal or waveform, or oscillation, at a desired frequency or within a specified frequency range. They are used for many applications for which the frequency or frequency range of the signal must be adjusted frequently, or for which different, predictable output waveforms or syllables are required. Programmable oscillators can be fine-tuned with external control signals to deliver periodic output signals of variable frequency, duty cycle, and other characteristics, such as rising and falling edges. They are critical components in many digital circuits, digital devices and systems, including computers and communication devices. In many digital systems, they play an important role in clock synchronization, data transfer and data acquisition.

The synthesizer is able to generate any programmable frequency from the crystal reference and the phase detector compares the frequency of the output waveform with the reference frequency. Once the frequencies are matched, the phase detector sends a control voltage to the synthesizer to adjust the frequency of the output waveform.

The SIT9005ACE1G-25SJ also incorporates an internal oscillator coupled with a voltage-controlled oscillator (VCO), providing the flexibility to tune the output frequency. Additionally, the device contains a digital programmable counter, which is used to select one of the sixteen predetermined frequencies. The frequency is adjusted by changing the voltage applied to the VCO.

The SIT9005ACE1G-25SJ is designed for easy programming and configuration. It is provided with an easy-to-use application software and allows for flexible frequency selection and programmable functions. Additionally, the SIT9005ACE1G-25SJ has an extremely low power consumption and supports a wide supply voltage range.
