Abstract
A mechanism for dynamic skew correction in a multi-lane communication link includes a receiver unit including, for each of the lanes, a first-in first-out (FIFO). The FIFO may store received symbols to locations pointed to by a write pointer and output to downstream logic, symbols stored at locations pointed to by a read pointer. The receiver may also include a symbol drop unit that disables the write pointer in response to receiving a start alignment symbol, and enables the write pointer in response to receiving an end alignment symbol. The receiver also includes an alignment unit that disables the read pointer in response to detecting that the end symbol has been received at least one lane but not all lanes. In addition, the alignment unit may enable the read pointer in response to a determination that the end symbol has been received on all lanes.
