Patent 7305047 was granted and assigned to Lattice Semiconductor on December, 2007 by the United States Patent and Trademark Office.
A receiver for high-speed serial communication that uses an interface such as XAUI is disclosed with automatic lane assignment. The receiver analyzes incoming data packets and determines the lanes based on the data packets. The lanes are then automatically reordered. The receiver allows the lanes to be connected to the receiver arbitrarily, thereby providing additional layout freedom to circuit board and ASIC designers.
