Abstract:
A method and apparatus for adapting, in parallel, two operating parameters associated with an equalizer circuit is disclosed. A control circuit may be configured to initialize a first operating parameter to an initial value, and modify a second operating parameter based upon the initial value of the first parameter. In response to determining a peak amplitude of an output signal of the equalizer circuit is less than a threshold value, the control circuit may be further configured to select a new value for the first operating parameter and adapt, in response to the change in the first operating parameter, the second operating parameter based on a performance metric of the equalizer circuit.
