Abstract

See full text

Apparatus and associated methods relate to generating a programmable differential threshold with a common mode signal derived from a received signal, and comparing a differential component of the received signal to the programmable differential threshold signal to improve signal loss detection accuracy in the presence of noise. In an illustrative example, the comparison may be performed in a signal loss detection circuit. The signal loss detection circuit may, for example, process a received input signal in an independent path in parallel with a main signal path. The programmable differential threshold may be set to a predetermined level as a function of an acceptable noise level. Based on the comparison, some implementations may advantageously respond to received signal loss, which may result from, for example, a signal path interruption.
