Abstract
An apparatus includes an interface and a training circuit. The interface may be configured to transmit signals to/from a plurality of I/O channels. The training circuit may be configured to generate a training voltage on a current one of the I/O channels, read an output of an eye monitor slicer to determine voltage transition values corresponding to the training voltage at a plurality of sampling times, map the voltage transition values to coefficients for the current I/O channel and determine the coefficients for each of the I/O channels. The training circuit may comprise the eye monitor slicer. The voltage transition values may correspond to an interference response for one of the I/O channels. The coefficients may be applied as feedback to cancel the interference.
