Ultra-Low Power Fractional PLL IP in in TSMC(12/16nm FFC, 22nm ULP/ULL, 28nm HPC+)

M31 Ultra-Low Power Fractional PLL is a general purpose frequency synthesizer with input reference frequency range from 10 to 240 MHz and 3:1 output frequency range. The PLL core is a typical Type-II PLL. The fractional part of the output frequency is achieved by using a programmable 3rd-ord sigma delta modulator. The PLL core operates on core supply voltage with embedded LDO for excellent supply rejection in noisy SoC applications. It is designed for easy usage and simple integration without complex configurations.
