Introduction to Programmable Oscillators

Programmable oscillators are electronic devices capable of generating and cycling a periodic, sine wave-based signal at a predetermined frequency. They are widely used in many electronic devices, e.g. cellular phones, cameras, computer parts, medical instruments, etc. The most common types of programmable oscillators are the analog and digital types.Analog oscillators use a voltage-controlled oscillator to generate a steady, analog signal. This signal is then cycled and regulated with the help of a frequency synthesizer, or phase-locked loop (PLL). Digital oscillators use digital components to generate a digital signal, which is then converted to an analog signal by a digital-to-analog converter (DAC).Because of their different components, programmable oscillators can be part of a much larger system and they can be used to provide functions like phase-locked loop (PLL), frequency synthesis, and clock synchronization.

Working Principle of SIT1602AIR3-30S

The working principle of the SIT1602AIR3-30S is based on a phase-locked loop (PLL) circuit. The PLL circuit consists of a phase detector, a charge pump, a voltage-controlled oscillator (VCO) and a frequency divider.The phase detect compares the phase of the input frequency and the reference frequency. The charge pump supplies dc voltage to the VCO to adjust frequency. The VCO generates a frequency as close as possible to that of the reference frequency. The frequency divider divides the output frequency of the VCO to get the desired output frequency.In short, the SIT1602AIR3-30S oscillator is a highly accurate, stable, and versatile programmable oscillator that is able to meet the most demanding requirements in embedded applications. It is simple to use, reliable and low cost, making it ideal for a wide range of applications.
