Oscillators

Oscillators are electronic circuits that generate a steady alternating current, usually of a very precise frequency, by using an electronic circuit such as a vacuum tube, transistor, or integrated circuit. They are the basis for many important types of electronic equipment including radios, television receivers, communication systems, radar systems, computers, and laboratory instrumentation. Oscillators are also used for timing or controlling other types of circuitry, and are the basis of almost all digital logic devices.

The SIT8209AC-3F-28E-166.666000X is a type of oscillator that is widely used in many commercial and military applications. It is a low-frequency (100 kHz to 100 MHz) voltage-controlled crystal oscillator (VCXO) with a wide operating temperature range (-25°C to +85°C). The oscillator is a highly-stable, low-power, and cost-effective device with excellent performance and reliability. It is designed for a variety of applications such as frequency hopping and jamming-resistant radios, navigation systems, radio frequency (RF) synthesizers, and access control systems.

Working Principle

The SIT8209AC-3F-28E-166.666000X oscillator is a voltage-controlled oscillator (VCO) with a crystal resonator as its frequency-determining device. Its operation is based on a closed-loop feedback mechanism. When a voltage is applied to its input terminal, the crystal resonator is caused to vibrate producing a frequency output in accordance with the crystal characteristics. The frequency is then compared with the applied voltage. If there is any difference between the two, an error signal is generated which is then applied to a comparator and the output frequency is adjusted accordingly.

The SIT8209AC-3F-28E-166.666000X oscillator also features a high-stability crystal and a precision voltage-controlled circuit to ensure a low-phase-noise signal. This also enables the device to operate over a wide frequency range while maintaining excellent frequency stability and accuracy.
