578S144CAT Working Principle

The 578S144CAT oscillator is a voltage-controlled oscillator (VCO) in which output frequency can be varied in accordance with a control voltage. Its working principle is based on the fact that, when a certain voltage is applied to an oscillator, the frequency that is produced is proportional to that voltage. A voltage-controlled oscillator consists of a variable frequency divider, an amplifier, and a voltage-controlled oscillator. The frequency of the voltage-controlled oscillator is determined by its components and the applied voltage, and its output frequency is controlled by the applied voltage.

The 578S144CAT oscillator has a power VCO, an FM discriminator, and a Programmable Frequency Synthesizer (PFS). The VCO is responsible for changing the output frequency in accordance with the input voltage and generates the reference signal for the PFS circuit, which is then processed by the FM discriminator. The outputs of the FM discriminator and the power VCO are compared to determine the correct frequency for the oscillator.

In conclusion, the 578S144CAT oscillator is a cost-effective and reliable oscillator used in many applications. Its application field includes radio, broadcast, satellite networks, cellular phone base stations, and VSAT. It is a voltage-controlled oscillator in which output frequency can be varied in accordance with a control voltage.
