Abstract:
A method for reducing signal edge jitter in an output signal from a numerically controlled oscillator includes processing an input signal with a first accumulator to provide a first accumulator output signal and continuing to use a carry in the processing of the input signal with the first accumulator in the event of an overflow. The method further includes processing the input signal with a second accumulator to provide a second accumulator output signal and rejecting a carry in the processing of the input signal with the second accumulator in the event of an overflow. The method further includes outputting the second accumulator output signal at an output of the numerically controlled oscillator and synchronizing the second accumulator using the first accumulator output signal.
