PLL Synthesizers and VCOs

Linear Technology/Analog Devices

Linear Technology/Analog Devices ultralow noise integer-N and fractional-N phase locked loop (PLL) synthesizers provide excellent phase noise and the industry’s lowest spurious performance. The LTC6946 and LTC6948 reduce overall system cost, design complexity and solution size by integrating a high performance 6GHz-plus low phase noise VCO along with an ultralow noise charge pump, reference divider and phase-frequency detector. These devices are the PLL of choice in solutions requiring ultra-short frequency settling times thanks to the fast on-chip VCO calibration algorithm.
