Introduction
Programmable Oscillators are electronic components that generate an oscillating electronic signal. They are used in a variety of ways in many different applications, most commonly as a timing element or RF signal generator. The SIT8008BCU3-28N is one such example of a programmable oscillator designed specifically for use in the professional audio/visual markets. In this article, we will discuss the application field and working principle of the SIT8008BCU3-28N.

Application Field
The SIT8008BCU3-28N is designed for use in professional audio/visual markets. Its primary applications include the driving of loudspeakers and transducers, the modulation of RF signals and the generation of AM and FM radio signals. Additionally, due to its programmable and flexible design, the SIT8008BCU3-28N can be used in applications such as frequency synthesis and base-band signal generation. The oscillator also provides low-jitter, low-noise operation, making it suitable for use in High Definition, Digital Video and Audio applications.

Working Principle
At the heart of the SIT8008BCU3-28N is a CMOS-based programmable oscillator. It operates on the principle of utilizing a crystal resonator, along with an oscillator circuit, to generate a periodic, or oscillating, electrical signal. The crystal resonator is a quartz crystal that vibrates when an electrical voltage is applied across it. The oscillator circuit then uses this vibration as its reference frequency, and this frequency is then divided or multiplied to create the output frequency. The frequency and phase of the output can then be programmed and adjusted using a variety of parameters, including voltage control, current control, temperature compensation, and trimming of the crystal frequency.

Conclusion
The SIT8008BCU3-28N is a highly programmable and flexible programmable oscillator specifically designed for use in the professional audio/visual markets. Its applications include driving loudspeakers and transducers, generating AM and FM radio signals, and frequency synthesis. Its operation principle consists of a quartz crystal resonator, along with an oscillator circuit, that uses a reference frequency generated by the crystal to generate the output frequency. With its low-jitter and low-noise operation, the SIT8008BCU3-28N is a ideal choice for High Definition, Digital Video and Audio applications.
