System and method to blacklist equalization coefficients in a high-speed serial interface

摘要

A serial interface comprises a receiver including a first input compensation module with a first setting that selects a first value from among a plurality of first values for a first input characteristic of the receiver, a memory to store a first blacklist value from among the first values, and a control module to select each of the first values, except for the first blacklist value, to evaluate an indication of a performance level of the receiver for each of the selected first values, and to select a particular first value based upon the indications of the performance level of the receiver.
