Abstract
The invention notes that higher speed serial links have higher power draws than lower speed serial links, but that the power draw on a fully loaded higher speed link is lower (Fig. 3b) than on multiple lower speed links (Fig. 3a) providing the same overall bandwidth. The invention discloses lane bonding circuitry to aggregate/multiplex multiple streams on to the faster serial lane to reduce total power draw. The invention discloses overwriting sync words/alignment markers in at least one of the streams in order to allow the streams to be identified and distinguished. The streams may be CPRI (Common Public Radio Interface) channels. The alignment markers may be K28.5 comma markers. The invention may be implemented as a data conversion gasket between an ASIC core and a high speed serial link.
