Mention XORing to get the clock. |
Clarify things, add a few more links. |

Line 1:
'''Data strobe encoding''' (or '''D/S''' encoding) is an encoding scheme
which uses two signal lines (e.g., wires in a cable or traces on a [[printed circuit board]]), ''Data'' and ''Strobe'', with the property that
either Data or Strobe changes its logical value in one [[clock cycle]], but never both.
This allows for easy [[clock recovery]] with a good [[jitter]] tolerance by [[XOR]]ing the two signal lines.
Data strobe encoding is used on the signal lines in the [[IEEE 1394]] (aka FireWire 400) system.
