SIT1602BI-21-XXN-12.000000E Application Field and Working Principle

The SIT1602BI-21-XXN-12.000000E oscillator is typically used as a timebase in electronic timekeeping applications. The oscillator is a two-wire device that uses a quartz crystal as the frequency-determining element. Its operation is based on the piezoelectric effect, which is the response of a crystalline material to an applied electric field. The crystal has two electrical characteristics that must be taken into account for its proper operation: electrical capacitance and mechanical stiffness.The device consists of a quartz crystal and two oscillator circuits housed in one package. The quartz crystal, which serves as a resonant element within the oscillator circuit, contains two electrodes that are connected to the oscillator circuitry and act as a capacitance. As the device is excited with a voltage, the crystal\'s resonance frequency oscillation begins. The crystal can act as both an inductor and a capacitor depending on the generated frequency. The oscillator circuit then amplifies the signal and drives an output signal whose frequency matches that of the quartz crystal.When the SIT1602BI-21-XXN-12.000000E oscillator is used, the input frequency and the output frequency are very closely matched. This enables precise timekeeping applications and high accuracy over a long period of operation. The device is also extremely low power; it consumes only a few milliwatts of power.The device also has several unique features that make it ideal for electronic timekeeping applications. One feature is a power management system that allows the oscillator to remain active even when the voltage supplied to the device is below the specified operating voltage range. This makes it possible for the device to remain active even if the power source to the oscillator is interrupted for any reason. Additionally, the device also has a built-in PLL circuit which helps to improve frequency stability over time and temperature.The SIT1602BI-21-XXN-12.000000E oscillator is an ideal choice for applications which need accurate timekeeping. Its superior accuracy, low power consumption, and a number of unique features make it a great choice for designing timekeeping circuits.
