Abstract:
A device for converting at least four parallel data streams on respective input data lines into one serial data stream on a fiber optic data line, the device comprising:a first multiplexer for multiplexing at least two of the parallel data streams into a first intermediate output stream;a second multiplexer for multiplexing at least two other of the parallel data streams into a second intermediate output stream;a serializing transmitter coupled to the first and second multiplexers for serializing the first and second intermediate output streams into the serial data stream, anda signal for synchronizing the serializing of the first and second intermediate output streams and tagging output data in the serial data stream as corresponding with data from each of the respective input data lineswherein the signal includes a cycle having a first phase and a second phase, the first phase for tagging output data in the serial data stream from two of the respective input data lines and the second phase for tagging output data in the serial data stream from another two of the respective input data lines.
