Programmable Oscillators are a type of electronic component designed to generate stable and precise frequency signals that can be adjusted or programmed to meet specific requirements. These devices serve as the heartbeat for many electronic systems, providing a clock signal that ensures synchronous operation across various components. Essential for applications that demand customizable frequencies, programmable oscillators allow users to set the output frequency on-demand, either through external programming methods or via an internal microcontroller. Due to their flexibility, they are commonly used in system designs that might require fine-tuning during operation or post-production, such as telecommunications equipment, consumer electronics, and embedded systems.
Main characteristics of Programmable Oscillators include their ability to offer a wide frequency range, low jitter and phase noise, and the convenience of on-the-fly frequency adjustment, which eliminates the need for multiple fixed-frequency oscillators. They also contribute to reduced inventory overheads since one programmable unit can replace several fixed-frequency components. Manufacturers of these versatile devices include SiTime, Microchip Technology, and TXC Corporation, among others.
