Serial data validity monitor

摘要: A data detection system includes, in part, a CID detector, DC balance monitor and transition density detector. The detector is configured to detect whether the received stream includes exceeding predetermined threshold count. imbalances incoming that may be indicative of errors data. minimum exists during given time period. If violation detected by any one these three detectors, an out-of-frame signal asserted. scrambled SONET or SDH stream.
