'''Data strobe encoding''' (or '''D/S''' encoding) is an encoding scheme for transmitting data in [[digital circuit]]s.
It uses two signal lines (e.g. wires in a cable or traces on a [[printed circuit board]]), ''Data'' and ''Strobe''. These have the property that either Data or Strobe changes its [[Truth value|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 line values.<ref>{{cite book |last=Parkes |first=Steve |date=2012 |title=SpaceWire User's Guide |url=https://www.star-dundee.com/sites/default/files/SpaceWire%20User's%20Guide.pdf |___location= |publisher=STAR-Dundee Limited |page=52 |isbn=978-0-9573408-0-0 |author-link= }}</ref>
There is an equivalent way to specify the relationship between Data and Strobe.
