Oscillators, in the context of electronic components, are devices that generate a periodic wave-shaped output, typically a sine wave or square wave. They serve as the heartbeat for many electronic devices, providing a steady rhythm that controls timing and synchronization. Their main function is to generate an output signal without an input signal. Oscillators have a wide range of uses, from simple ticking sounds in toys and clocks to more complex uses such as controlling the frequencies of radio and television broadcasters, and synchronizing operations in computers and servers.
For specific applications, it is important to select the correct type of oscillator. Some are designed to handle high frequencies, while others work best at lower frequencies. The main characteristics of oscillators include frequency stability, amplitude stability, and output waveform quality. Notable manufacturers of oscillators include Texas Instruments, ON Semiconductor, and Analog Devices.
