Abstract:
The present invention is directed to data communication. According to a specific embodiment, the present invention provides technique for loss of signal detection. A loss-of-signal detection (LOSD) device determines an analog signal indicating signal strength by subtracting a threshold offset voltage from an incoming signal. The analog signal is then processed by a switch network of an output stage circuit, which provides a digital output of loss of signal indication at a low frequency (relative to the incoming signal frequency). There are other embodiments as well.
