Abstract:
A circuit for filtering inter-symbol interference in an integrated circuit is described. The circuit comprises a first stage coupled to receive digital samples of an input signal. The first stage generates first decision outputs based upon the digital samples. A second stage is coupled to receive the digital samples of the input signal. The second stage comprises a filter receiving the first decision outputs and generating second decision outputs based upon the digital samples of the input signal and detected inter-symbol interference associated with the first decision outputs. A method of filtering inter-symbol interference in an integrated circuit is also described.
