Claims (3)
- シリアル伝送方式のシステムバスに接続可能な信号伝送回路であって、
前記システムバスの送信クロックのパルス波形のエッジ毎に当該システムバスの複数の伝送路のうち一つの伝送路だけの伝送信号のパルス波形を変化させる一方で当該複数の伝送路のうち他の複数の伝送路の伝送信号のパルス波形を各々異なる所定の送信クロック数分の時間差で変化させることで当該システムバスの各伝送路のパルス波形の変化時点について当該各伝送路間で時間差を設けるタイミング調整回路を備えて当該各伝送路の伝送信号が当該各伝送路間で当該変化時点が同時とならない単独の伝送信号としたこと
を特徴とする信号伝送回路。 - 前記変化時点は、前記パルス波形の立ち上がり時点及び立ち下がり時点であることを特徴とする請求項1に記載の信号伝送回路。
- 前記システムバスの各伝送路から前記タイミング調整回路に供される伝送信号のパルス波形を整形する位相同期回路をさらに備えたこと
を特徴とする請求項1または2に記載の信号伝送回路。
