Abstract
A method for compensating NCO jitter by changing a step value used to increment an accumulator in the NCO to make up for inaccuracies, or jitters. In one approach, a remainder in the accumulator may be monitored and a compensated clock close to the current edge of an ideal clock may be generated. In another approach, a compensated clock close to the next edge of the ideal clock may be generated after the current edge of the ideal clock is missed. The step value may be stored in a memory, which may be a register. A jitter compensator may include a comparator for monitoring the remainder in the accumulator or a detector for detecting whether an ideal clock has been missed. The jitter compensator may also change the step value to a step value for a faster clock to compensate jitter.
