Deskew and clock domain crossing for multilane link

Abstract

Systems and methods for communicating data via a multilane data link from a first clock domain to a second clock domain, where the data streams of a multilane link are clocked into FIFO deskew buffers using clock signals that are recovered from the data streams themselves. Each data stream is clocked into the deskew buffer with the clock signal recovered from that data stream. The data is clocked out of the deskew buffers using the clock signal of a target clock domain so that the data streams clocked out of the deskew buffers are synchronized with each other and with the clock signal of the target clock domain (the target clock signal) to eliminate the need for a separate clock domain crossing buffer.
