Working Principle of SIT1602BC-23-33E-20.000000D Oscillator

The basic working principle of SIT1602BC-23-33E-20.000000D oscillator is based on phase-locked loop (PLL) technology. PLL works in two different frequency domains, low frequency and high frequency, which work together to reduce phase noise and improve frequency stability.

In the low frequency domain, a voltage controlled oscillator (VCO) is used to produce a precise output frequency in proportion to the input control voltage. The output frequency of VCO is compared to a reference frequency in the phase-frequency detector (PFD) and the error signal is passed to the loop filter to provide an voltage control signal to the VCO.

In the high frequency domain, a loop filter is used to reject the input noise and limit the bandwidth. The output from the loop filter is generally used as the input control voltage of VCO. This voltage control voltage is kept stable by the open loop gain of the system. The loop filter and the VCO together form the PLL oscillator.

SIT1602BC-23-33E-20.000000D oscillator uses the technique of frequency multiplication to achieve high frequency and low phase noise performance. Frequency multiplication happens when the PLL is operated in a linear mode, i.e. the VCO frequency is locked to the reference frequency. The PLL can then be used to multiply the reference frequency by an integer number and generate a much higher output frequency.

SIT1602BC-23-33E-20.000000D oscillators also employ a frequency divider circuit, which can divide down the frequency of high frequency signals and pass it through the loop filter. This can further reduce the noise and improve the frequency stability of the system. The frequency divider circuit can also be used to adjust the frequency range of the oscillator.

SIT1602BC-23-33E-20.000000D oscillators also feature other features to enhance their performance, such as temperature controlled oscillators, or TCXOs, that can compensate for oscillator’s frequency variation with the temperature. These oscillators also have low power consumption, wide frequency range, and programmable frequency settings.

In conclusion, SIT1602BC-23-33E-20.000000D oscillators are a type of oscillator that uses PLL technology to perform ultra-fast timing signals. These oscillators feature excellent phase noise, frequency stability, wide frequency range and long term frequency accuracy. These oscillators are used in various applications and are becoming more widely used with the advancement of wireless communication systems.
