ABSTRACT:
Method and apparatus for ensuring synchronism among modules of a distributed digital system (DDS) to a master clock signal is disclosed. The master clock signal is distributed at a frequency f.sub.c /N, and circuitry associated with each module multiplies the distributed master clock signal by N to provide a desired sync frequency f.sub.c to each module.
