M31 Digital-PLL is a core-power only programmable phase-locked loop (PLL) for frequency synthesis. It supports multiple modes of operation for several application conditions, such as Phase-locked loop (PLL) /Fractional-N phase-locked loop (FNPLL) /Spread spectrum clocking (SSC)/ Oscillator (OSC). M31 Digital-PLL has excellent immunity to power supply noise, making it ideally suited for use in noisy ASIC/SoC environments and is available as a single macro for easy integration into any ASIC/SoC.
