Working Principle of SIT1602BC-73-30S-33.333330D Oscillator

The SIT1602BC-73-30S-33.333330D oscillator works on the principle of phase locked loop (PLL). The SIT1602BC-73-30S-33.333330D PLL consists of a voltage-controlled oscillator, a phase detector, a low pass filter and a voltage-controlled amplifier. The voltage-controlled oscillator (VCO) generates signal with a frequency that is proportional to the input voltage. The frequency of the signal generated by the VCO is compared to the input signal by the phase detector. The output signal of the phase detector is filtered by the low pass filter and then fed to the voltage-controlled amplifier. The output of the VCO is adjusted by the voltage-controlled amplifier according to the filtered output of the phase detector.

The PLL is in the locked state when the phase of the output of the VCO is identical to the phase of the input signal, and the frequency of the output signal is equal to the frequency of the input signal. The SIT1602BC-73-30S-33.333330D PLL oscillator can achieve a stable frequency output with minimal jitter under wide temperature range.
