Oscillators

Oscillators are electronic circuits that produce a periodic, oscillating electronic signal, often a sine wave or a square wave. They are used in virtually all electronic devices, including computers, communication systems, power sources, and a wide variety of consumer products. Oscillators are also used in clinical and industrial applications, such as ionizers, timers, and frequency meters.

Working Principle

The SIT8209AC-8F-18E-212.500000X oscillator is a highly integrated device that includes a high-precision frequency synthesizer and a low-power voltage-controlled oscillator (VCO). The frequency synthesizer is comprised of a 6-bit digital-to-analog converter (DAC), a programmable reference crystal, and a 32-bit phase accumulator, in order to generate voltage-controlled frequency tunable signals. This allows the oscillator to be finely tuned over a wide frequency range. The frequency synthesizer combined with the VCO produces a precise and stable RF signal.

The VCO is the core of the oscillator, and is composed of two-stage low-noise amplifiers (LNA), an inductor-capacitor tank (LC tank) to form the oscillator cavity, and a voltage-controlled varactor diode to adjust the frequency of the signal. The LC tank is responsible for providing the oscillator with an adjustable resonance. The resonance cavity of the oscillator is formed by the inductor-capacitor tank, while the voltage-controlled varactor-diode is used to adjust the frequency of the signal. The varactor diode changes its capacitance with the changing of the control voltage.

The oscillator’s frequency-tuning range is defined by the frequency synthesizer, and the frequency stability is determined by the VCO’s phase noise performance. The oscillator’s phase noise and jitter are critical parameters in understanding its long-term stability. As the oscillator ages, its frequency stability may vary, but the VCO’s ability to follow its reference signals will remain consistently low.

In conclusion, SIT8209AC-8F-18E-212.500000X oscillator provides excellent phase noise performance and low power consumption. Its highly integrated design is suitable for applications ranging from clock and data producers to wireless and telecom equipment. The oscillator is ideally suited for telecommunications, data/network, mobile/cellular, and broadcast equipment markets, as the frequency synthesizer and the VCO offer precise frequency control and low phase noise.
