It can also be used in the baseband modulation of sidebands in frequency modulated (FM) transmitters and receivers. In computing applications, it can be used for phase-locked loops (PLL) to ensure that both the fundamental and its harmonics are locked into a fixed frequency. In measuring and sensing applications, the SIT1602BI-71-25S-20.000000D can be used to generate a fixed frequency for use in a timer or voltage reference. In telecommunications, the oscillator can be used in frequency synthesizers or phase locked loops (PLL) for frequency control.

Working Principle of SIT1602BI-71-25S-20.000000D

The working principle of the SIT1602BI-71-25S-20.000000D is based on the frequency adjustment technique called voltage-controlled or frequency-tunable oscillators (VCOs). This situation involves the use of a variable capacitor coupled with the voltage control Input (VCI) and the oscillator feedback circuit. Whenever the voltage at the input is changed, the frequency of the oscillating signal changes accordingly. The oscillator receives a periodic positive feedback and gets it through either an inductor or capacitor, which subsequently produce a waveform of the required frequency.

The VCI is connected to the variable capacitor, allowing the parameter to be adjusted and then the oscillator output frequency changes. Generally, a capacitance of between 15 and 25 pF is chosen for most applications. The output from the capacitor is fed into the mixer, where a variable current source determines the level of the output. This stage is referred to as the voltage-controlled amplifier (VCA). A resistor is usually placed between the input and the output to provide a stable feedback loop.

Once the feedback loop is established, the oscillator works like a voltage-controlled oscillator, with a fixed frequency reference. The output of the oscillator is taken from the frequency dividers, which divide the output frequency by a fixed value and pass it to the Voltage Control Output (VCO). This is then used to adjust the voltage across the variable capacitor, thus allowing the frequency output of the oscillator to be changed.

The SIT1602BI-71-25S-20.000000D oscillator is an important component in many electronic circuits since it is very easy to use, reliable, and cost-effective.
