Open the CIPO recordAbstract From the Canadian patent
A method and apparatus are provided for receiving parallel digital data signals and an aligned frame pulse. The frame pulse occurs at a regular interval which is a multiple of the data clock period. A multiple clock sampling scheme includes sampling the frame pulse using a plurality of phase-shifted clock signals selecting several clock signals which are centered on the frame pulse and therefore the data. Then, sampling the data using the selected clocks, taking a majority value of the multiple samples and aligning the sampled data with a locally generated frame pulse using an elastic store.

Why it's free to use
- Filed May 23, 1990 and granted April 9, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 23, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 23, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
