ABSTRACT:
We describe a voltage level coding system and method. The voltage level coding system includes a level encoder having an input to receive data segments coded using a first code and an output to supply second data codes indicating one of 2Nplus at least one additional voltage level to which each data segment is assigned. A converter converts the second data codes into such voltage levels. A controller output supplies the voltage levels. A method for coding digital data includes determining a first data transition, generating a code that includes at least one additional level that minimizes data skew in the first data transition, and coding the first data transition with the additional level in the code.
