Pre-programmed OscillatorsCrystals, oscillators, and resonators are electronic components that are used to generate precise frequencies and timing signals. These components are commonly used in electronic devices to provide a reference frequency for the operation of the device, such as in clocks, radio transmitters, and microcontrollers.
Pre-programmed oscillators are oscillators that have been programmed to output a specific frequency or set of frequencies. These oscillators are typically used in applications where the device or system needs to operate at a specific, fixed frequency, and where the user does not need to be able to adjust the frequency of the oscillator. Pre-programmed oscillators are typically more convenient and easier to use than adjustable oscillators, which require the user to manually set the frequency. Pre-programmed oscillators are available with a wide range of frequencies and output types, to meet the needs of different applications.
