Abstract
A frequency synthesizing system includes a clock generator to generate a reference clock signal, a frequency doubler to generate a frequency-doubled clock signal in response to rising edges and falling edges of the reference clock signal, a frequency multiplier to generate a frequency-multiplied clock signal in response to either rising edges or falling edges of the frequency-doubled clock signal, and a fractional-N synthesizer coupled to the frequency multiplier to generate an output clock signal in response to the frequency-multiplied clock signal.
