Oscillators are electronic circuits that produce a defined and regular waveform, either for time keeping or as a generator of frequency signals. TD-22.1184MDE-T is a commonly used oscillator for many applications.

TD-22.1184MDE-T is first and foremost a temperature-compensated crystal oscillator (TCXO). It is designed for use in satellite navigation systems and other applications where clock stability is critical. The oscillator is available in several different frequencies, as well as several grades of temperature stability and aging performance.

The TCXO works on the principle of crystal oscillation. When a voltage is applied to a quartz crystal, it vibrates at a frequency determined by its size, shape, and internal structure. The frequency of the vibration remains constant and is very precise.

Given a stable voltage supply and a good quality crystal, the frequency of the oscillator will remain constant over a wide temperature range. This is achieved by compensating the change in crystal frequency caused by changes in temperature through the use of a thermistor. The thermistor senses the changes in temperature and makes corrections to the oscillator circuit to keep the frequency stable.

The result is that the TD-22.1184MDE-T has a very tight frequency accuracy, typically ±2.5ppm over full temperature range of -40°C to 85°C. The frequency stability of the oscillator varies according to the grade chosen, typically between ±3ppm to ±10ppm over 10 years.

The TD-22.1184MDE-T is ideal for use in applications with strict stability requirements such as cellular base stations and satellite navigation systems. In addition, the TD-22.1184MDE-T is suitable for a range of other precision timing applications including high speed networks, industrial control systems, and in the medical industry.

To summarize, the TD-22.1184MDE-T is a temperature-compensated crystal oscillator (TCXO) offering high accuracy and stability for use in precision timing applications. It works on the principle of crystal oscillation, where a voltage is applied to a quartz crystal, leading to a vibration whose frequency is determined by its size, shape, and internal structure. Thanks to a thermistor, the frequency remains stable and consistent over a wide temperature range. It is a great choice for applications with strict stability requirements including cellular base stations, satellite navigation systems, high speed networks, industrial control systems, and medical instruments.
