Title: Digital transmitter with data stream transformation circuitry

Abstract: A transmitter with data stream transformation circuitry is described. The transmitter has a first driver and a second driver. Each driver has an output for a respective analog signal. A summation circuit combines respective analog signals from the first driver and the second driver. A data selection circuit processes at least two data streams. Each data stream corresponds to a time sequence of digital data symbols. The data selection circuit selectively couples at least one of the data streams to at least one of the drivers during each time interval of a sequence of time intervals, thereby applying a linear transformation to the data streams. A finite state machine controls the data selection circuit during each time interval of the sequence of time intervals.
