Patent ID: 7502411

Claim:
An adaptive equalization circuit for equalizing at least two signals, comprising: at least two equalization filters, each coupled and configured to equalize a different one of the at least two signals in a manner at least partially determined by an equalization control signal, wherein a first of the equalization filters is coupled and configured to generate a first equalized signal in response to a first of the at least two signals in a manner at least partially determined by the equalization control signal; and control circuitry, coupled and configured to generate the equalization control signal in response to the first equalized signal but not in response to any equalized signal generated by any of the equalization filters other than said first of the equalization filters, and to assert the equalization control signal to all the equalization filters, wherein said first of the at least two signals is a predetermined fixed pattern signal, said first of the equalization filters is configured to generate an equalized fixed pattern signal in response to the predetermined fixed pattern signal, and the control circuitry is configured to generate the equalization control signal in response to the equalized fixed pattern signal.
