摘要: An integrated circuit includes a plurality of receivers, each having clock and data recovery circuit. A first local in receiver can be caused to produce test which simulates condition tested, while second the receivers that is use place reference receiving sequence at its input. The circuits include control loops responsive loop signals modify selected generate response selective one (i) corresponding signal for normal operation or during test, (ii) applied case produced.
