The CY22381SXI-146T is a frequency synthesizer that works on a fundamental principle of supplying a base frequency from an oscillator and multiplying it by fractions or multiples. It can generate up to four output frequencies from one single device by controlling the internal PLL circuits. The device is based on a Phase Locked Loop (PLL) frequency synthesis system. A PLL is an electronic circuit consisting of two parts: an oscillator and a feedback loop. The oscillator generates the base frequency, while the feedback loop adjusts the current frequency in response to an external input. This is done by comparing the current frequency to the reference frequency and adjusting the oscillator so they match in phase and frequency.
