A data equalization system includes a data clock input configured to receive a clock signal. There is an input node operative to receive a data signal of transmission symbols that change state synchronously with the clock signal. There is a first tap coupled to the input node. A second tap is configured to receive a variation of the data signal. At least one of a weight of the first tap or a weight of the second tap is modulated by a dynamic control parameter that repeats synchronously with each transmission symbol.
