ABSTRACT:
A two-wire bus is used to de-skew XAUI lanes of a single charnel received at independent chips. One wire of the bus is transmits an alignment signal generated by a master and used by slaves coupled to the bus to detect misalignment of their data from data received at the master. The other wire transmits an error signal generated by any slave that detects a misalignment.
