Patent ID: 7158727

Claim:
An optical transmitter comprising: a predetermined plurality of parallel data inputs; a clock generator having a reference clock input producing a plurality of output clock signals of differing phases in synchronism with the reference clock input; a plurality of parallel to serial data converters, each coupled to a corresponding one of said parallel data inputs, each parallel to serial data converter receiving an output clock signal of a predetermined phase from said clock generator with each parallel to serial data converter receiving said output clock signal of the same predetermined phase from said clock generator, each of said parallel to serial data converters having a buffer loaded in parallel in synchronism with a read clock a predetermined fraction of said output clock signal of said predetermined phase to trigger data input and output serially in synchronism with said output clock of said predetermined phase; a clock output multiplexer connected to said clock generator receiving said plurality of output clock signals of differing phases and outputting a selected one of said plurality of output clock signals of differing phases; and an electrical to optical converter connected to said plurality of parallel to serial data converters and said output clock multiplexer for generating an optical signal corresponding to said output of said plurality of parallel to serial converters in synchronism with said output clock of said predetermined phase.
