Abstract

본 발명은 타이밍 복원시 계산량을 저감시켜 고속 데이타 수신에 적합하도록한 데이타 송수신시스템의 타이밍 복원 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timing recovery apparatus for a data transmission / reception system which is adapted to receive high-speed data by reducing the amount of calculation during timing recovery.

이러한 본 발명은 입력되는 아날로그 수신신호를 그에 상응하는 디지탈 신호로 변환하는 아날로그/디지탈 변환기와, 아날로그/디지탈 변환기에서 출력된 신호를 전치 필터링하여 심볼 주파수 신호를 추출하기 위한 성분만을 출력하는 전치 필터와, 전치 필터에서 출력된 신호중 선택적으로 위상을 비교하여 위상차 신호를 발생하는 위상 비교부와, 위상 비교부에서 출력된 신호를 정규화하여 아날로그/디지탈 변환기의 샘플링 클럭 조절신호로 출력하는 정규화부를 구비한다.The present invention relates to an analog-to-digital converter for converting an input analog signal into a corresponding digital signal, a pre-filter for pre-filtering a signal output from the analog / digital converter and outputting only a component for extracting a symbol frequency signal, A phase comparator for generating a phase difference signal by selectively comparing phases among the signals output from the predistorter; and a normalizer for normalizing the signal output from the phase comparator and outputting the sampled clock adjustment signal of the analog / digital converter.
