M31 Ultra-Low-Power Fractional-N PLL IP
M31 LPFPLL is a low-power programmable fractional-N (LPF), phase-locked loop (PLL) for frequency synthesis. It can support a wide range of output frequencies with fine resolution, as well as supporting multiple input reference frequencies. M31 LPFPLL is ideal for use in noisy ASIC/SoC environments due to the excellent supply noise immunity. The lock-detect flag supports real-time monitoring of the phase-locked status. With embedded ESD power clamp circuits and internal initial sequence applied to release from complex configurations and settings, M31 LPFPLL is available as a single macro and can be integrated into any ASIC/SoC easily.
