Claim:
1. An apparatus that compensates for misalignment on a synchronous data bus, the apparatus comprising: a replica radial distribution element, configured to receive a first signal, and configured to generate a second signal, wherein said replica radial distribution element comprises replicated propagation path lengths, loads, and buffering of a radial distribution network for a strobe; a bit lag control element, configured to measure a propagation time beginning with assertion of said first signal and ending with assertion of said second signal, and configured to generate a value on a lag bus that indicates said propagation time, wherein said bit lag control element comprises: a synchronous lag receiver, configured to receive one of a plurality of radially distributed strobes and a data bit, and configured to delay registering of said data bit by said propagation time, said synchronous lag receiver comprising:
