Abstract
A clock signal generator having a DDS circuit which adds up a frequency word with a particular frequency and generates an output pulse when an overflow occurs. To reduce jitter, a parameter value corresponding to the ideal overflow time of the DDS circuit is determined and an output pulse generating circuit determines, in dependence on the parameter value and using a further, higher frequency, a corrected time for the output pulse and outputs the output pulse at this corrected time.
