Patent ID: 8516331

Claim:
A transmitter configured to manipulate an input data stream to properly format an output data stream for transmission over a channel disposed on a backplane at a baud rate of 10.3125 GHz or above, the transmitter comprising: a scrambler configured to remove sequences of digital zero or digital one values from the input data stream to provide a scrambled data stream; a forward error correction (FEC) encoder configured to generate and append redundant symbols to the scrambled data stream to provide a FEC encoded data stream; a serial-to-parallel module configured to de-serialize the FEC encoded data stream and distribute the FEC encoded data stream over two or more parallel FEC encoded data streams, wherein at least one of the redundant symbols generated by the FEC encoder has been generated based on data sent over two or more of the parallel FEC encoded data streams; a line code encoder configured to modulate one of the parallel FEC encoded data streams using a pulse amplitude modulation (PAM) scheme having an order M to provide a modulated data stream; and a TX linear filter configured to adjust the modulated data stream to compensate for high-frequency attenuation of the channel to provide the output data stream.
