Patent number: 6760397Abstract: A programmable-divider provides a lower-speed transition signal to effect a synchronized load of a new divisor value during a safe-load period of the programmable-divider, such that the division occurs using either the prior divisor value or the new divisor value, only. A combination of in-phase and reverse-phase counter stages are used to position the divisor-independent period of each counter stage so that an edge of at least one of the lower-speed counter-enabling signals occurs during a period when all of the counter stages are in a divisor-independent period. The preferred selection of in-phase and reverse-phase counter stages also maximizes the critical path duration, to allow for the accurate division of very high speed input frequencies.Type: GrantFiled: August 6, 2002Date of Patent: July 6, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Hongbing Wu, Rainer Gaithke
