  • Ultra-wideband loss of signal detector at a receiver in a high speed serializer/deserializer (SERDES) application
    Patent number: 9252928
    Abstract: An apparatus comprising a first loss of signal circuit, a second loss of a signal circuit and a gate circuit. The first loss of a signal circuit may be configured to (i) receive an input signal containing a series of data and (ii) generate a first indication signal when the input signal is operating within a first frequency range. The second loss of signal circuit may be configured to (i) receive the input signal and (ii) generate a second indication signal when the input signal is operating within a second frequency range. The gate circuit may be configured to generate an output signal in response to either the first indication signal or the second indication signal being active.
