Abstract:
1. An apparatus for transmitting synchronization headers into multiple high-speed serial data communications streams comprising: an input channel receiving a number B of symbols in parallel, a first output channel transmitting a number A of symbols in parallel, a second output channel transmitting a number B of symbols in parallel, a control unit, a header sequence generator generating a sequence of H header symbols in succession when triggered by the control unit, a temporary storage unit storing a number H×B of symbols, a first multiplexer connecting one of two signals to the first output channel, and a second multiplexer connecting one of two signals to the second output channel, wherein the control unit triggers the header sequence generator every time a synchronization header must be transmitted; wherein the temporary storage unit stores symbols incoming on the input channel for a number H of symbols after the header sequence generator is triggered; wherein the first multiplexer selects the header sequence generator output for a number H of symbols after the header sequence generator is triggered, then it selects the output of the temporary storage unit; and wherein the second multiplexer selects the header sequence generator output for a number H of symbols after the header sequence generator is trigger, then it selects the input channel.
