ABSTRACT:
There is provided a shift clock generator for phase-shifting a shift clock by inserting insertion pulses into the shift clock, wherein an insertion pulse generating section has a compensation memory for storing compensation data for calculating a number of insertion pulses to be inserted into the shift clock with respect to a phase difference preset value based on a phase shift amount, a number-of-pulses calculating section for integrating the compensation data stored in an address range of the compensation memory to calculate a number-of-insertion pulses data based on the phase difference preset value and a pulse generating section for generating the insertion pulses based on the number-of-insertion pulses data.
