Low Power Fractional PLL is a general purpose frequency synthesizer with an input reference frequency range from 10 to 240 MHz and 3:1 output frequency range. The PLL core is a typical Type-II PLL and the fractional portion of the output frequency is achieved by using a programmable 3rd-ord sigma delta modulator. The PLL core operates on IO supply voltage for excellent supply rejection in noisy SoC applications. It is designed for easy usage and simple integration, eliminating the need for complex configurations.
