Oscillators

An oscillator is an electronic circuit that produces a repetitive, cyclic, self-sustaining electrical signal. Oscillators are widely used in various industries, such as audio and radio communications, navigation and guidance systems, metering system, motor speed control, medical instrumentation, and more.

SIT1602BI-32-28E-40.500000T: Application Field and Working Principle

SIT1602BI-32-28E-40.500000T is a type of low power crystal oscillator. This oscillator is ideal for applications requiring low power consumption, such as monitoring systems, automotive, industrial and consumer applications. This oscillator is able to work at relatively high temperatures compared to other types of oscillators.

The SIT1602BI is a 32.500000 MHz oscillator. It uses an AT-cut quartz crystal as the resonator and incorporates a voltage regulator in its design which ensures reliable operation at temperatures ranging from -20°C to +85°C. This oscillator also includes an integrated 32.768 kHz circuit to reduce power consumption and optimize energy.

The working principle of the SIT1602BI is based on the fact that when a quartz crystal is subjected to an alternating electrical field, it vibrates at a specific frequency. This frequency is determined by the crystal\'s physical properties and external factors such as the applied voltage and surrounding temperature.

The quartz crystal in the SIT1602BI is the resonator. Its vibrating frequency is determined by the piezoelectric effect; when a voltage is applied to the crystal, it expands and contracts, creating an alternating electrical field. This alternating electrical field is then fed back into the amplifier, producing an oscillating signal at the frequency of the quartz crystal.

The SIT1602BI also incorporates a phase-locked loop (PLL) circuit. It is used to maintain a constant frequency over a range of temperatures and voltages. The PLL circuit is composed of an oscillator, a frequency divider and a voltage-controlled oscillator (VCO). The oscillator generates a clock signal which is then divided by the frequency divider to generate a reference signal. The VCO compares the reference signal with the oscillator\'s output and adjusts the output frequency accordingly.

In conclusion, the SIT1602BI-32-28E-40.500000T is a low power crystal oscillator ideal for applications that require minimal power consumption. It works by producing an electrical signal from a quartz crystal which is determined by its physical properties and the surrounding environment. The oscillator also includes a PLL circuit to maintain a constant frequency and voltage.
