Oscillators

Oscillators are circuits that produce a continuous output signal. They are widely used in electronic devices for timekeeping, frequency displacement and other various uses. The TC-14.7456MCE-T is an oscillator with a special set of characteristics.

TC-14.7456MCE-T Application Field

The TC-14.7456MCE-T is a temperature compensated oscillator (TCXO) that can operate over a wide temperature range with low phase noise and excellent stability. It is widely used in critical timing applications such as military, aerospace, communications and other industrial applications. This TCXO was designed for applications that require a stable signal over a wide range of environmental conditions. It is suitable for use in applications such as radars, telemetry, navigation systems, and satellite communications.

TC-14.7456MCE-T Working Principle

The TC-14.7456MCE-T relies on a quartz crystal to maintain its accuracy and stability. A quartz crystal is a piezoelectric material that can vibrate at a very specific and constant frequency. The frequency of the quartz crystal is determined by the physical size and geometry of the crystal. The TC-14.7456MCE-T is designed to operate over a wide temperature range of -40°C to +85°C without the need for external voltage trimming. The circuit includes a temperature sensor and temperature compensation circuitry to maintain the accuracy of the oscillator across the temperature range. The temperature compensation circuitry adjusts the oscillator frequency based on the temperature to ensure that the frequency remains constant. The stability of the output signal is excellent, with a typical frequency drift of only 0.0002%/°C over the full temperature range. The TC-14.7456MCE-T also has very low phase noise (noise generated by the oscillator itself) of -178dBc/Hz at 10kHz offset.

Conclusion

The TC-14.7456MCE-T is an excellent choice for applications that require a stable output signal over a wide range of temperatures. The temperature compensation circuit maintains an excellent accuracy and stability over the rated temperature range, and the low phase noise ensures that the output signal is clean and free of interference.
