In a multi-channel apparatus, a first plurality of N channels support user data and associated error correction and a second plurality of channels each contain a unique p-bit symbol followed by N consecutive M-bit samples of each of the N data channels. The receiver or retriever apparatus regenerates a system clock from all channels and examines the respective bit streams to score each bit phase as a match or a non-match of the sample in the synch channel with each M bit sample of the respective N data streams, and for each such N channels a counter corresponding to the then current phase is incremented or decremented. Relative skew for the N channels is derived from the addresses of the first counter to overflow for each of the N channels.
