Oscillators are circuits in which the output voltage alternates in polarity, frequency and magnitude. This type of circuit works in such a way that it creates a frequency that is generated from the system, and the SIT1602BI-21-18N-33.330000E is an oscillator used for frequency synthesis and circuit applications.

Application Field

This oscillator can be used in many different areas with its wide frequency range. The synthesized frequencies it produces ranges from 1.2 MHz to 47 MHz in its standard model. This range can be changed slightly depending on the users need. Moreover, this oscillator can be applied in TV signal generators, communications base-stations, cable TV systems, satellite television, test equipments, etc. This oscillator can also be used for high stability clock sources, frequency synthesis modules, wireless bridge transceivers, etc.

Working Principle

This oscillator has an integrated microprocessor core that constant monitors and adjusts the output frequency to a certain range. It also has a voltage controlled oscillator (VCO) and a phase-locked loop (PLL) circuit which are incorporated on the oscillator. The VCO section is where the oscillator produces a signal frequency according to the voltage received, and the PLL circuit is responsible for making the frequency even more stable. Thus, the signal generated from the oscillator is of high stability and accuracy.

The SIT1802BI-21-18N-33.330000E oscillator also has a programmable divider and prescaler which facilitates its operations. The programmable divider circuit divides the signal generated from the VCO by a certain number which is determined by the user, while the prescaler is used to increase the range of the oscillator by dividing the frequency of the signal generated by a greater number.

This oscillator is highly suitable for digital applications where a stable and accurate signal is required, such as in television systems, communications, wireless systems, etc. This oscillator also has a low power consumption which means its operation won’t overheat and damage the system.
