Claims (1)

  1. クロックデータリカバリ回路と、デシリアライザと、シリアライザと、ＰＬＬ回路と、周波数検出器とを具備して、
    前記クロックデータリカバリ回路は受信信号と前記ＰＬＬ回路から生成されるクロック信号とに応答して、再生クロックと再生データとを抽出するものであり、
    シリアル・パラレル変換器としての前記デシリアライザは、前記再生クロックと前記再生データとからパラレル受信データを生成するものであり、
    パラレル・シリアル変換器としての前記シリアライザは、パラレル送信データと前記ＰＬＬ回路から生成される前記クロック信号とからシリアル送信信号を生成するものであり、
    前記周波数検出器は前記受信信号の周波数と前記クロック信号の周波数との差を検出することによって、前記ＰＬＬ回路に供給される周波数制御信号を生成するものであり、
    前記周波数制御信号に応答して前記受信信号の前記周波数と前記クロック信号の前記周波数との前記差を低減するように、前記ＰＬＬ回路は前記クロック信号の周期を制御する
    ことを特徴とする送受信装置。
