Patent ID: 7756487

Claim:
An apparatus for generating a local oscillator signal having an output frequency, comprising: an oscillator circuit operative to generate a first signal, said first signal having a frequency substantially equal to a rational multiplier L/N of said output frequency; a frequency divide by Q coupled to receive said first signal and operative to generate 2Q second signal phases at a frequency substantially equal to a rational multiplier L/(N*Q) of said output frequency; a pulse generator operative to generate a plurality of pulse signals from said 2Q second signal phases; a frequency divider by L coupled to receive said 2Q second signal phases and operative to generate a plurality of third signals; a selector operative to select, using time division multiplexing, one of said plurality of pulse signals as an output signal in accordance with a select control signal, said output signal having a frequency substantially equal to said output frequency; and control means for generating said select control signal as a function of said plurality of third signals and said output signal.
