Abstract
An out-of-band (OOB) signal detector is disclosed. The OOB signal detector may include a first node configured to receive an alternating current (AC) portion and a direct current (DC) portion of an electrical signal. The AC portion may include modulated OOB data carried by the electrical signal. The OOB signal detector may also include a current to voltage processing circuit configured to extract the AC portion of the electrical signal. The OOB signal detector may additionally include a limiting amplifier circuit configured to receive the extracted AC portion and to generate an amplified signal based on the extracted AC portion. The OOB signal detector may further include an analog-to-digital convertor circuit configured to sample the amplified signal and to generate a digital sample that represents the modulated OOB data.
