The mmWave PLL provided by CoreHW is a high-precision fractional-N PLL designed for use in demanding wireless communication systems and radar applications. Operating primarily between 19 and 81 GHz, it features an adaptable frequency synthesizer with low phase noise, suitable for fast frequency chirp generation in FMCW radar systems. The design itself is frequency-scalable, allowing for customization over a wide range of mmWave frequencies.\nThe PLL integrates several key components, such as frequency multipliers that extend the range to radar frequency bands between 38-40.5 GHz and 76-81 GHz. CoreHW's mmWave PLL also offers the capability of Linear Frequency Modulation, essential for applications needing reliable chirp modulation, alongside a built-in sequencer for calibration and testing.\nThe technology used in this PLL falls under GlobalFoundries' 22FDX™ process, which ensures low power consumption, operating from voltages of 0.8V for IO and 1.2V for the RF sectors, supporting an ambient temperature spectrum of -40 to 125 degrees Celsius. The compact design ensures minimization of the area required on silicon, enhancing its applicability in advanced automotive and communication infrastructure.
