Symmetrical pathways transport the first bit streams from the input ports to the data conversion circuits, wherein their transmission time(s) are substantially equal. A clock distribution circuit receives and symmetrically distributes a clock signal to data conversion circuits. A central trunk coupled to the clock port and located between a first pair of circuit pathways with paired branches that extend from the trunk and that couple to the data conversion circuits make up the clock distribution circuit. The distributed data clock signal latches data in data conversion circuits from the first to the second bit stream(s). | 11-15-2012 |
| 20150071311 | REFORMATING A PLURALITY OF SIGNALS TO GENERATE A COMBINED SIGNAL COMPRISING A HIGHER DATA RATE THAN A DATA RATE ASSOCIATED WITH THE PLURALITY OF SIGNALS - Various aspects provide for aggregating a plurality of signals to generate a combined signal. An aggregation component is configured for reformatting a plurality of first signals and combining the plurality of first signals to generate a combined signal that comprises a higher data rate than a data rate associated with the plurality of first signals. A transmitter component is configured for receiving the combined signal and generating one or more data streams based on the combined signal. In an aspect, the aggregation component is additionally configured for reformatting and/or combining the plurality of first signals and at least one second signal to generate the combined signal. In another aspect, a receiver component is configured for generating a pseudo signal at a data rate of the combined signal. In yet another aspect, a de-aggregation component is configured for recovering the plurality of first signals and/or the at least one second signal from the pseudo signal. | 03-12-2015 |
