It features excellent temperature stability and low jitter, making it suitable for fields of applications where consistent frequency accuracy and stability is required. It is mainly used in smart meters, medical equipment, industrial computer, optical transceivers, etc. It supports a wide range of frequencies from 1.7MHz to 501MHz.

Working Principle

The SIT1602BC-82-25N-4.000000T oscillator operates by a principle known as the "Phase-Locked Loop" (PLL). This system comprises a pair of oscillators coupled by a negative feedback system, which is designed to match the output frequency of one oscillator to the reference frequency of the other. This is done by adjusting the amplitude and phase of the feedback signal so that the output of one oscillator matches the phase of the other. When the two signals are synchronized, it forms a stable oscillation and a stable frequency is maintained.

The SIT1602BC-82-25N-4.000000T uses an integrated circuit as its active component. This IC contains a crystal oscillator, voltage-controlled oscillator, and an amplifier. The oscillator is regulated by the output of the voltage controlled oscillator, where a voltage-controlled voltage source (VCO) determines the frequency output of the oscillator. The frequency of the oscillator is maintained by a quartz crystal, whose frequency is predetermined and unadjustable. The amplifier is used to increase the signal strength.

Summary

The SIT1602BC-82-25N-4.000000T is a temperature compensation oscillator that is used in a variety of applications such as smart meters, medical equipment, industrial computer, and optical transceivers. It utilizes the powerful Phase-Locked Loop principle to provide consistent, precise, and stable frequencies within a wider range. Its integrated circuit consists of a crystal oscillator, voltage-controlled oscillator, and an amplifier, all of which help to create a stable frequency output.
