Oscillators

Oscillators are electronic circuits that generate regular pulses or oscillations. They find many applications in communications, control systems, navigation, power supplies, instrumentation, radar, and radio. The SIT8209AI-33-33E-166.666000X oscillator is a type of quartz crystal oscillator (XTAL) that features an oscillation frequency of 33 kHz and a pullability of 166.666 ppm.

Application

This crystal oscillator finds use in a wide range of applications. It is typically used for radio-controlled watches, digital clocks, counters, and measuring equipment. Its high accuracy makes it suitable for medical applications such as patient monitoring equipment and portable EEG machines. It can also be used in precision instruments, automatic meter reading systems, and portable IP devices.

Working principle

This oscillator works by vibrating a piece of quartz crystal at very high frequencies. The quartz crystal is cut and set inside a container filled with liquid. The crystal is connected to two electrodes at either end. When an electrical current is applied to the electrodes, the crystal vibrates and produces a voltage that is used as an oscillator signal.

The frequency of the signal depends on the size of the quartz crystal and its shape. The quartz crystal’s physical properties, such as frequency, are determined by the frequency of the input signal, the pullability, and the circuit’s dampening effect. This oscillator also features a temperature-compensated oscillator (TCO) that helps the oscillator maintain an accurate frequency over a wide range of temperatures.
