Oscillators are electronic components that produce a periodic, oscillating wave. The SIT1602BC-73-25S-40.500000E oscillator is a specialized oscillator designed for high-precision applications requiring long-term stability.

The SIT1602BC-73-25S-40.500000E oscillator utilizes a quartz crystal cut to a precise frequency and featuring excellent aging characteristics. The oscillator typically includes an input oscillator stage referred to as an inverter, an output amplifier, and an output buffer. The components are adjusted in a specific way to produce a highly stable output.

The oscillator is used in a variety of applications where accuracy and stability of timing functions is required, such as clocks, timed control signals, and frequency control. It can also be used in communications equipment and electroacoustical devices, such as radios.

The principle of operation is based on the quartz crystal piezoelectric effect. Quartz crystals are natural piezoelectric materials, meaning they generate a voltage when subjected to mechanical stress, which is a change in pressure. When a voltage is applied to the crystal, the reverse occurs—the crystal changes its shape.

When an AC voltage is applied to the quartz crystal, the crystal vibrates at a specific frequency based on its cut. This frequency is determined from the calibrated capacitance-to-frequency ratio and the resonance of the crystal. The output of the oscillator is the selected frequency of the crystal multiplied by the gain of the amplifier.

The oscillator also features excellent temperature compensation. The quartz crystal oscillator is a temperature-compensated design whereby a temperature sensor and a temperature-compensating capacitor are connected in series to the crystal. As the oscillator temperature changes, the capacitance of the capacitor increases or decreases, which alters the frequency of the oscillator and maintains the accuracy of the frequency.

The SIT1602BC-73-25S-40.500000E oscillator is designed for conditions where long-term stability and low phase noise are required. Fully calibrated with tight tolerance and high reliability, the oscillator ensures enhanced signal integrity and reliable operation in extreme environments.
