Oscillators: SIT1602BI-22-18S-27.000000D Application Field and Working Principle

The SIT1602BI-22-18S-27.000000D (SIT1602BI) oscillator is a high-frequency TCXO (temperature-compensated crystal oscillator) which enables frequency stability under varying levels of environmental change. Its high-frequency range makes it a popular choice for many purposes. This article will explore the application field of this oscillator and its working principle.

Application Field

The SIT1602BI oscillator is suitable for use in a wide range of applications where frequency stability is important. Commonly-used applications include communications, navigation, and scientific instruments. Additionally, the oscillator is used in consumer electronics products, such as mobile phones, audio systems, and other digital products.Due to its high frequency range, the SIT1602BI is especially suited for use in environments which require stability over long periods of time. It is also suitable for both commercial and military applications, as its frequency stability is not affected by environmental temperature changes. The frequency stability of this oscillator makes it an ideal choice for applications which need precise performance in harsh environments.

Working Principle

The SIT1602BI oscillator utilizes a quartz crystal as its driving element. When an alternating electrical signal is applied to the quartz crystal, it will vibrate in response. This vibration produces an oscillating electrical signal, which is the basis of this oscillator\'s output.The frequency of this oscillating signal is determined by the characteristics of the quartz crystal and the applied electrical signal. The frequency is also influenced by environmental factors such as temperature, with external temperature changes causing shifts in the frequency of the oscillating signal.To ensure that the frequency remains stable across a range of temperatures, the SIT1602BI oscillator utilizes a unique temperature-compensation mechanism (TCM). The TCM utilizes temperature sensors to monitor the external temperature, and it adjusts the oscillator\'s frequency in response. This ensures that the frequency remains stable even when external temperatures change.

Conclusion

The SIT1602BI oscillator is a high-frequency TCXO which enables frequency stability across a range of environmental factors. Its application field encompasses a wide range of purposes, from navigation and communication to consumer electronics, and its frequency stability makes it ideal for precise performance in harsh environments. The working principle of this oscillator is based on a quartz crystal which produces an oscillating electrical signal. In order to maintain the stability of this signal, a temperature-compensation mechanism is used to adjust the frequency in response to external temperature changes.
