A data transmission system receiver is disclosed which receives a formatted data stream (302) and operates in one of at least a first bandwidth mode and a second bandwidth mode. The formatted data stream (302) comprises a plurality of data edges (108, 110) and is sampled by a first clock signal (320). A plurality of clock edges (102 104) defining transitions from one logic state to another is used to define "early" and "late" data edge occurrences.

Why it's free to use
- Filed January 27, 1992 and granted November 24, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 27, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 27, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
