摘要:
In an embodiment of the present invention, a clock generator circuit is disclosed to include a phase locked loop (PLL) that is responsive to a reference frequency and operative to generate a single clock frequency and a clock signal quadrature output frequency and a clock signal in-phase output with the frequency of the clock signal quadrature output frequency and the clock signal in-phase output frequency being a fraction of the frequency of the single clock frequency. The PLL includes a single voltage controlled oscillator (VCO) that generates the single clock frequency. A plurality of dividers is included in the clock generator circuit and is responsive to the clock signal quadrature output frequency and the clock signal in-phase output frequency and generates multiple clock frequencies, each clock frequency being a unique frequency, each of the plurality of dividers generating an output, the final output of the plurality of dividers being synchronized to the reference frequency.
