Working Principle
The working principle of the SIT1602BI-72-25S-66.6000000 oscillator is based on the principle of quartz tuning fork crystal oscillation. Quartz crystals produce an electrical signal when they vibrate at their resonant frequency, and that signal is applied to a circuit, which converts it into an output frequency. The frequency of the output signal is determined by the size of the quartz tuning fork crystal and the amount of current supplied to the circuit.

The quartz tuning fork crystal is mounted on a brass holder, and the holder has two pins that connect to the circuit. With the PCB, the holder works as a resonant cavity for the crystal and the circuit amplifies the crystal signal into an output frequency.

The holder also has a spring that serves as a shock absorber and helps maintain the frequency stability of the oscillator. It also allows the holder to move slightly when the crystal is stressed so that the crystal can vibrate more freely. Additionally, the spring helps protect the oscillator from ESD and electromagnetic interference.

The output signal of the SIT1602BI-72-25S-66.6000000 oscillator is a square wave that is suitable for digital logic applications. The oscillator has a wide frequency range and offers low jitter and low phase noise performance, making it suitable for a variety of applications.

In conclusion, the SIT1602BI-72-25S-66.6000000 oscillator is an ideal building block for various electronic and communication systems. It offers excellent frequency stability over a wide temperature range, and provides low jitter and low phase noise performance that make it suitable for numerous applications.
