Description
Claims (4)
- 소인 재밍 변수정보를 저장하는 소인 재밍 변수 저장수단과, 주파수 소인을 위한 카운트 클럭을 공급하기 위한 분주수단과, 상기 소인 재밍 변수 저장수단에 저장된 소인 재밍 변수정보를 기반으로 하여, 상기 분주수단으로부터 공급되는 클럭에 따라 소인 주파수 카운트를 수행하는 카운트수단과, 상기 카운트수단의 현재 소인 주파수값과 소인밴드폭(SBW)의 1/2값을 감산하여 소인 주파수신호를 출력하는 감산수단과, 상기 카운트수단의 현재 소인 주파수와 소인 밴드폭 정보를 비교한 결과에 따라 상기 카운트수단을 업/다운 카운트 제어하는 카운트 제어수단을 포함하여 이루어지는 것을 특징으로 하는 주파수 소인회로.
- 제 1 항에 있어서, 상기 소인 재밍 변수 저장수단은 소인 밴드폭, 소인 증가폭, 소인주기, 소인형태 정보를 저정하기 위한 래치 및 레지스터로 이루어지는 것을 특징으로 하는 주파수 소인회로.
- 제 1 항에 있어서, 상기 분주수단은 MCLK를 소인주기(Ts)와 소인 증가폭(Sres)을 이용해서 분주하여 카운터수단에 클럭을 공급하는 것을 특징으로 하는 주파수 소인회로.
- 제 1 항에 있어서, 상기 카운트 제어수단은 상기 카운트수단의 현재 소인주파수와 소인 밴드폭(SBW)의 상한값을 비교하는 제1비교수단과, 상기 카운트수단의 현재 소인 주파수와 소인 밴드폭(SBW)의 하한값을 비교하는 제2비교수단과, 상기 제1비교수단 및 제2비교수단의 비교결과에 따라 상기 카운트수단을 업카운트 모드 또는 다운 카운트 모드로 전환시키는 플립플롭과, 상기 제1비교기와 제2비교기의 출력을 소인 형태에 따라 플립플롭의 세트 또는 리세트 신호로 공급하기 위한 게이트 및 버퍼를 포함하여 이루어지는 것을 특징으로 하는 주파수 소인회로.
