Abstract:
1. A microelectronic element, comprising: a transmitter having a frequency response capable of peaking and controllable in accordance with a plurality of operational parameters; a storage operable to store the plurality of operational parameters for controlling the frequency response of the transmitter under each of a plurality of operating conditions corresponding to the plurality of operational parameters; at least one sensor operable to detect one of the plurality of operating conditions; and a control circuit operable in response to a change in the detected operating condition to use one of the stored operational parameters corresponding to the detected operating condition to control the frequency response of the transmitter, wherein said frequency response is represented by a Bode plot for each of the plurality of operational parameters; wherein the plurality of operating conditions comprises values of at least two variables; and wherein the transmitter is operable to transmit data serially over a cable external to the microelectronic element and the at least two variables includes at least one of (a) a length of a cable to which the transmitter is coupled to transmit output and (b) a data transmission rate for transmitting data by the transmitter.
