Oscillators

An oscillator is an electronic circuit that generates an electrical signal, often sinusoidal, at a well-defined frequency, usually determined by components in the circuit itself. A standard oscillator uses electronic circuits or other methods to generate an AC signal at a frequency generally specified by adjusting an electronic component, such as a resistor, a capacitor, and a transistor. In this article, we will discuss the application field and working principle of SIT8208AC-21-18S-33.000000Y oscillator.

• Medical imaging systems
• Industrial and automotive electronics
• Home entertainment and home automation systems

This oscillator is also used in radio and radar systems, robotics, audio and video systems, power control systems, security and access control systems, and a variety of consumer products.

Working Principle

The SIT8208AC-21-18S-33.000000Y oscillator circuit mainly consists of an oscillator transistor (2SC2180-K), a feedback resistor (220Ω), and a feedback capacitor (470pF). The circuit operates by feeding a portion of a sinusoidal wave output from the collector of the oscillator transistor back to its base through the feedback resistor and capacitor. This causes a phase shift of the waveform that is 180 degrees out of phase between the input and the output of the circuit, and at a certain frequency (determined mainly by the feedback components), the waves build up on each other in a positive feedback loop and the oscillations can become self-sustained.

The SIT8208AC-21-18S-33.000000Y oscillator is widely used for its low jitter, high frequency stability, and low power consumption. The 3.3V operating voltage makes it ideal for low-voltage applications. With a fast settling time (6 nSec) and wide frequency stability range (±50 ppm), this oscillator is suitable for systems that require high-speed digital circuits.
