Circuit and method of encoding and decoding digital data transmitted along optical fibers

A method of transmitting encoded data over a channel, comprising the steps of:

• complementing input data in response to an encode invert signal for transmission as encoded data over a first channel;
• generating said encode invert signal according to an encoding algorithm and transmitting a transmitted clock encoded by said encode invert signal over a second channel;
• receiving said encoded data and complementing said encoded data in response to a decode invert signal for providing an output signal;
• and
• decoding said transmitted clock to recover said decode invert signal.

An integrated data transmission circuit, comprising:

• a data transmitter coupled for receiving input data and complementing said input data upon receiving a first state of an encode invert signal for transmission as encoded data over a first channel;
• an encoder for generating said encode invert signal to said data transmitter according to an encoding algorithm and transmitting a transmitted clock encoded by said encode invert signal over a second channel;
• a data receiver coupled for receiving said encoded data and complementing said encoded data upon receiving a first state of a decode invert signal for providing an output signal of said data receiver;
• and
• a decoder coupled for receiving said transmitted clock and recovering said decode invert signal from said transmitted clock.
