Abstract
In an asymmetrically terminated communication system, the power consumed to transmit a particular bit value is adjusted based on whether the bit being output is the second, third, fourth, etc. consecutive bit with the same value after a transition to output the particular bit value. The adjustment of the power consumed to transmit the two or more consecutive bits with the same value may be made by adjusting the driver strength during the second, or subsequent, consecutive bits with the same value. The adjustment of the power consumed is performed on the bit value that consumes the most DC power and the other value is typically not adjusted.
