Abstract
In described embodiments, adaptive equalization of a signal in, for example, Serializer/De-serializer transceivers by a) monitoring a data eye in a data path with an eye detector for signal amplitude and/or transition; b) setting the equalizer response of at least one equalizer in the signal path while the signal is present for statistical calibration of the data eye; c) monitoring the data eye and setting the equalizer during periods in which received data is allowed to contain errors (such as link initiation and training periods) and periods in which receive data integrity is to be maintained (such as normal data communication).
