A frequency reduction or phase shifting circuit has an input receiving an input data stream having an input frequency and a representation of desired output frequency. A splitter splits the input data stream into a plurality of split signals each at a frequency of the desired output frequency. A plurality of catchers identify valid bits of each respective split signal. A shifter shifts valid bits identified by at least some of the catchers by a predetermined number, which establishes a de-serialization level for frequency reduction or phase shifting. An output provides an output data stream at the desired output frequency.
