Oscillators

The SIT8208AI-31-33S-32.768000X oscillator is designed for the specific application of providing a consistent frequency over a large period of time. This product line has been developed and optimized to be used in many different industries that require a stable timing source. Examples of these include banking, financial services, telecom, GPS, medical, and industrial. The specific product discussed in this paper has a frequency of 32.768kHz.

An oscillator is a circuit which produces a periodic waveform. An oscillator contains an amplifier, a frequency-determining device called a resonator, and a feedback network that drives the amplifier. The oscillator itself has two main parts: the power supply and the logic circuit. The power supply provides the necessary voltage and current for the oscillator’s operation while the logic circuit is responsible for generating the required frequency. The logic circuit works by providing a voltage or current signal to the oscillator’s resonator which causes it to vibrate and produce an output frequency.

This particular oscillator’s resonator consists of a quartz crystal. Quartz crystals are highly stable and can be used in the circuit to provide a very consistent frequency. This frequency can be adjusted to within a few parts per million of the desired frequency at temperatures between 0 and 70 degrees Celsius, making it ideally suited for applications that require a stable timing source.

The crystal has a built-in capacitance that is important in determining the frequency of the oscillator. By adjusting this capacitance the frequency of the oscillator can be adjusted, allowing it to be tuned to the required frequency. The capacitance of the crystal is influenced by temperature, however, so a temperature-compensating circuit is also included to ensure that the oscillator retains its accuracy over a wide range of temperatures.

In addition to the crystal, the SIT8208AI-31-33S-32.768000X oscillator also includes additional components to ensure that the device is immune to interference from noise and electromagnetic interference. For this purpose, the oscillator includes a shield to protect the quartz from interference, a low-noise amplifier and a low-noise filter. These components help to ensure that the oscillator maintains an accurate output frequency even in hostile environments.

The SIT8208AI-31-33S-32.768000X is an impressive piece of engineering that is capable of providing reliable frequency and timing for any application. This makes it ideal for a wide range of applications, particularly those that require accuracy and stability in their timing. Despite its size, its features and performance make it ideal for industrial, commercial and medical applications that require a stable clock source.
