The technology of the TC-12.500MBD-T oscillator may appear quite specialized to the layperson, but is actually a simple application of basic physics. A quartz crystal is built into a precision oscillator circuit and then used to generate a crystal frequency which is held to within ±10 ppm even under more extreme temperatures.

What Is an Oscillator?

An oscillator is a device that produces an electrical signal that varies with time at a specific frequency. Oscillators play a key role in the development and operation of electronic devices, such as computers, televisions, and radios.

What Is the TC-12.500MBD-T Oscillator and How Does It Work?

The TC-12.500MBD-T oscillator is a miniature quartz-based oscillator that operates at a frequency of 12.5 MHz. The oscillator is made up of two components: an oscillator circuit and a quartz crystal.The quartz crystal is a precision "clock" that produces a highly stable, frequency-determining crystal frequency. This frequency is held to within ±10 ppm even under more extreme environmental conditions, such as temperature and vibration.The oscillator circuit is then used to amplify the crystal frequency and transform it into electrical signals. These electrical signals are then used to control the frequency and phase of other electrical components.
