Moreover, it presents a Stability of ±0.5ppm/20°C maximum, a Low Aging Rate of ±0.1ppm/year maximum, and a Low Noise Floor of -145dBc/Hz at 10kHz.

Application Fields of 7W25070010 TCXO

Oscillators in general can be applied to health and medical equipment, especially when quicker and better diagnoses are needed. This is due to their high frequency stability, permitting accurate measurement of time or frequency and therefore having accurate output results. In this particular case, the 7W25070010 TCXO provides all the references given earlier, so it is specially suitable for a range of applications that need high temperature stability.

In the telecommunications industry, for instance, the 7W25070010 TCXO can be used in many gsm and umts systems as it is able to provide a lower GSM phase noise to improve the signal-to-noise ratio at the receptor, thus avoiding frequent dropouts and maintaining a good quality communication. Additionally, this type of oscillator can also be applied in Wi-Fi systems, GPS, and other short-range wireless communication. Moreover, they can also be employed for audio applications such as synthesizers, studio monitors and recording consoles.

Working Principle of 7W25070010 TCXO

The 7W25070010 TCXO is based on the construction of the Crystal Oscillator, which has a crystal resonator connected in parallel with a capacitor. The crystal is usually a quartz crystal cut in an exact shape and size so that it has electric properties for resonance. When an electric signal with a certain frequency is applied to the crystal resonator, it will start oscillating because of the resonance phenomenon that occurs when the frequency of the applied electric signal is equal to the natural resonant frequency of the crystal. The capacitor acts as a load and helps tune the frequency of the crystal to the desired value.

The main difference between this 7W25070010 TCXO and a standard crystal oscillator is the temperature compensation. This oscillator includes an integrated circuit that has a temperature sensing element to sense the variation in temperature and act as a feedback system, adjusting both voltage and impedances and thus providing accurate output frequencies even when the environment temperature varies.

Conclusion

7W25070010 TCXO is a type of Temperature Compensated Crystal Oscillator that has all the good features of its family, namely Frequency, Stability, Aging Rate and Noise Floor, and thus serves to efficiently work in a range of temperature-based applications.
