Claims (1)
害を検出する障害検出回路において、上記伝送路
の受端側に並設され、上記デイジタル差動信号の
状態に応じて互いに逆極性の２値信号をそれぞれ
出力する一対のレシーバーと、この両レシーバー
出力の排他的論理和を出力する排他的論理和回路
を備えたことを特徴とする障害検出回路。 In a fault detection circuit that detects a fault in a transmission line that transmits digital differential signals in a balanced manner, the fault detection circuit is installed in parallel on the receiving end side of the transmission line and generates binary signals of opposite polarity depending on the state of the digital differential signal. A fault detection circuit characterized by comprising a pair of receivers each outputting an output, and an exclusive OR circuit outputting an exclusive OR of the outputs of both receivers.
