Abstract
The present invention is directed to data communication system and methods. More specifically, embodiments of the present invention provide an apparatus that receives data from multiple lanes, which are then synchronized for transcoding and encoding. A pseudo random bit sequence checker may be coupled to each of the plurality of lanes, which is configured to a first clock signal A. Additionally, an apparatus may include a plurality of skew compensator modules. Each of the skew compensator modules may be coupled to at least one of the plurality of lanes. The skew-compensator modules are configured to synchronize data from the plurality of lanes. The apparatus additionally includes a plurality of de-skew FIFO modules. Each of the de-skew compensator modules may be coupled to at least one of the plurality of skew compensator modules.
