SIT3907AC-2F-33NZ-24.576000T application field and working principle

Oscillators are electronic components that generate a periodic signal of constant amplitude and frequency over a predefined range. As such, they are commonly used to generate a regular pulse signal for timing or synchronization purposes. Temperature compensated crystal oscillators (TCXOs) are used for accurate timing requirements and are most commonly used for telecom, navigation and communications applications. The SIT3907AC-2F-33NZ-24.576000T is an example of a TCXO.

Application

The SIT3907AC-2F-33NZ-24.576000T is suitably used in synthesizers, cellular base stations, local area networks, mobile telephone systems, pagers, radio, broadcasting applications, and applications that require low offset and stability. It is particularly designed for frequency stability and hold-over over wide temperature ranges. With an extremely low aging characteristic, this crystal oscillator is ideal for frequency or timekeeping applications sensitive to temperature variation.

Working Principle

The SIT3907AC-2F-33NZ-24.576000T is a quart oscillator, based on an inverter operating at 24.576 MHz. It is made up of a specialized semiconductor device connected to a quartz crystal and two or three capacitors. The frequency of the oscillator is determined by the characteristics of the quartz crystal and the capacitors used. The crystal typically operates in the high frequency range. The quartz crystal, or piezoelectric material, is the heart of the oscillator as it is the converting element that converts electrical signals into a mechanical vibration.

When the crystal is connected to a voltage source, an electric current is driven through the crystal that induces a mechanical oscillation of a specific frequency. This mechanical oscillation is matched to the frequency of its load capacitor to form an oscillator circuit with a predetermined output frequency. The oscillator then produces a continuous, accurate, sine-wave output signal with respect to its input voltage and crystal.

Conclusion

The SIT3907AC-2F-33NZ-24.576000T is a highly reliable, wide temperature range TCXO capable of precisely generating frequencies from 24.576MHz. This crystal oscillator is highly suitable for use in applications that require high accuracy and stability over wide temperature range. It is particularly recommended for applications such as broadcasting, telecommunications, navigation and communications.
