IntroductionOscillators are electronic components that produce a signal that oscillates between two levels or maintains a steady state. They are used in many applications, from clock signals for microprocessors to time-based controllers for machine tools. The SIT1602BI-21-28S-38.400000E is one type of oscillator, used mainly in industrial and commercial applications. In this article, we will discuss the application field and working principle of the SIT1602BI-21-28S-38.400000E.Application Field of SIT1602BI-21-28S-38.400000EThe SIT1602BI-21-28S-38.400000E is a temperature controlled crystal oscillator (TCXO) designed for use in a variety of industrial and commercial applications. The device is designed to provide highly reliable, stable frequency operation over a wide temperature range. Because of its low power consumption, excellent frequency stability, and shock resistance, it is widely used in telecommunications equipment, navigation instrumentation, automotive telematics systems, and consumer electronics.Working Principle of SIT1602BI-21-28S-38.400000EThe SIT1602BI-21-28S-38.400000E consists of an integrated circuit and a crystal resonator. The integrated circuit works as an oscillator to generate the output signal, and the crystal resonator provides the reference frequency. The crystal oscillator has an oscillation frequency determined by the characteristics of the crystal, while the integrated circuit can be adjusted to achieve the desired frequency.The device also uses a temperature-controlled oscillator, which allows for better frequency accuracy and stability over a wide temperature range. This is achieved by having the temperature sensor inside the oscillator, which monitors the ambient temperature and adjusts the oscillation frequency accordingly. This ensures that the output signal remains accurate and stable despite changes in the ambient temperature.ConclusionThe SIT1602BI-21-28S-38.400000E is a temperature-controlled crystal oscillator designed for use in industrial and commercial applications. It features low power consumption, excellent frequency stability, and shock resistance. The device works by having the integrated circuit generate the output signal and the crystal resonator provide the reference frequency. The temperature-controlled oscillator inside the device helps maintain accurate and stable frequency output even when the ambient temperature changes.
