Oscillators

Introduction

An oscillator is an electronic circuit or device that produces periodic, oscillating electronic signals, often used in communication technology as well as in various audio-visual and other electronic applications. Oscillators are used as frequency generators for radio transmitters and receivers, as clocks in digital devices, and as signal sources for digital filters and other processing modules. They are also used in many automotive and industrial applications, where they help stabilize and control the speed and amplitude of various processes.This article will focus on the application field and working principle of the AST3TQ-T-19.200MHZ-50-C-T2 oscillator.
