Abstract
The slew rate of signals output from an integrated circuit is selectively controlled to optimize the quality of the output data signal depending upon whether the communication channels require a faster or slower slew rate. Faster slew rates may be utilized when the communication channels are prone to attenuation, while slower slew rates may be implemented in the communication channels when crosstalk is more of a concern.
