Circuit and method for filtering intersymbol interference for SERDES applications

摘要

A circuit for filtering intersymbol interference in an integrated circuit is described. This circuit consists of a digital sample (x_kA first stage (308) coupled to receive the first stage (308). The first stage generates a first decision output based on the digital samples A second stage (310) is coupled to receive the digital samples of the input signal. The second stage includes a first determination output , And detects the intersymbol interference (i (t)) associated with the digital samples of the input signal and the first decision output_kA filter (350) for generating a second determination output (output data) based on the first determination output (output data). A method of filtering intersymbol interference in an integrated circuit is also described.(FIG.
