Multi-Lane Data Reception Device Deskew Synchronization

The patent applies preliminary action by inserting deskew codes and timing adjustment information into the header of each communication link before data transmission begins. This allows the reception device to pre-calculate and prepare timing corrections for each link, compensating for propagation delay differences before they cause synchronization issues. The timing adjustment information is embedded in advance in the header structure, enabling proactive synchronization rather than reactive correction.

The patent implements feedback by using the deskew codes in the header to provide timing information back to the reception device. The reception device measures the actual arrival timing of data from each link and uses the embedded deskew codes to calculate required timing adjustments. This feedback mechanism allows continuous timing synchronization across multiple links, ensuring that data from different communication paths arrives at the reception device in the correct temporal order.

The patent uses the header structure as an intermediary element that mediates between independent communication links. The deskew codes embedded in each link's header serve as intermediary timing information that allows independently transmitted data to be synchronized at the reception device. This intermediary mechanism enables each link to operate independently with flexible timing while still achieving overall synchronization through the mediating header information.

The patent applies parameter changes by dynamically adjusting the timing interpretation of data from different links based on the deskew codes in their headers. Each communication link can maintain its own transmission parameters and timing characteristics, but the reception device uses the embedded timing information to transform and align these different parameters into a unified synchronized data stream, effectively changing the timing parameters post-reception.
