Abstract:
A loss-of-signal detector includes digital and analog monitoring of incoming data. The incoming signal is compared digitally to at least one predetermined pattern that may indicate a loss of signal, and also is monitored by an analog detector that detects transitions in the data. If the digital comparison fails to match any of the at least one predetermined pattern, or if transitions are detected by the analog monitoring, even if the digital comparison produces a pattern match, then loss of signal is not indicated.
