Abstract

In one embodiment, a method may determine a number of data transitions occurring in a forbidden zone at each of a first and second slice levels and adjust a slice level offset for an amplifier based on the number of data transitions at the first and second slice levels. Furthermore, a phase window of the forbidden zone may be adjusted to attain a desired bit error rate for a receiver.
