Improved jitter performance is realized in a desynchronizer for obtaining an asynchronous digital signal e.g. a DS3 signal, from a received, synchronous digital signal e.g. a SONET STS-1 signal. The improved jitter performance results from the use of a unique dynamic bit leaking arrangement in conjunction with a digital phase locked loop and desynchronizing elastic store. An optimum bit leak interval is obtained by controllably leaking a greater number of shorter interval STS-1 bits than the number of received pointer adjustment bits.Additionally the affect of random pointer adjustments and the superposition of randomly received pointer adjustments on a periodic sequence of received …

Why it's free to use
- Filed August 27, 1992 and granted July 14, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 27, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 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.
