우리는 대칭 구조의 지연 생성기를 갖춘 새로운 유형의 위상 보간 직접 디지털 신시사이저(DDS)를 개발했습니다. 새로운 DDS는 더 낮은 스퓨리어스 신호를 생성한다는 점에서 사인 출력 DDS와 유사하지만 사인 조회 테이블이 필요하지 않습니다. 대칭 구조의 지연 생성기는 DDS 누산기의 MSB(최상위 비트)에서 주기적인 지터를 줄입니다. 대칭 구조를 통해 지연 발생기가 매우 정확한 지연 타이밍을 생성할 수 있으며 회로 상수를 조정할 필요가 없습니다. 실험 결과는 스퓨리어스 신호 레벨이 누산기의 레벨보다 낮은 수준으로 감소되는 주파수 합성기 작동을 확인합니다.

vol. E82-C, no. 7, pp. 1067-1072, July 1999, doi: .
Abstract: We have developed a new type of phase interpolation direct digital synthesizer (DDS) with a symmetrically structured delay generator. The new DDS is similar to a sine output DDS in that it produces lower spurious signals, but it does not require a sine look-up table. The symmetrically structured delay generator reduces the periodic jitter in the most significant bit (MSB) of the DDS accumulator. The symmetrical structure enables the delay generator to produce highly accurate delay timing and eliminates the need to adjust the circuit constants. Experimental results confirm frequency synthesizer operation in which the spurious signal level is reduced to less than that of the accumulator.
