Mode-conversion digital canceller for high bandwidth differential signaling

Abstract

Systems and methods for recovering rapidly from a mode-conversion of a common mode interference. One exemplary transceiver includes: a slicer configured to generate slicing decisions and slicing errors based on a differential signal, transmitted at a rate above 500 Mbps, which is received from a second transceiver; and a common mode sensor analog front end (CMS-AFE) configured to sense a common mode component of the differential signal. The CMS-AFE is coupled to a fast-adaptive mode-conversion canceller (FA-MCC) configured to generate a compensation signal that compensates for differential interferences that are correlated with the common mode component. Wherein, within less than 1 millisecond from an occurrence of a differential interference that causes the packet loss to exceed 10% as a result of the mode-conversion, the transceiver is configured to utilize the slicing errors to adapt the FA-MCC to a level that reduces the packet loss rate to below 1%.
