Abstract

A high-speed serial data interface includes a transmitter and a receiver. The transmitter includes a feed-forward equalization (FFE) module. The FFE module has a main tap and at least one secondary tap. In a first mode, a sum of absolute values of a main tap compensation value and a secondary tap compensation value of each one of the at least one secondary tap is equal to one. In a second mode, the main tap compensation value has a unity gain equal to one, and each secondary tap compensation value is greater than or equal to the secondary tap compensation value in the first mode divided by the main tap compensation value in the first mode.
