ABSTRACT:
A timing generating apparatus for generating a timing signal which changes at desired timing includes a first waveform generating unit for generating a first basic waveform whose value changes only at desired change timing of a basic frequency, a PLL for generating a sampling clock whose frequency is an integer multiple of the basic frequency and whose phase is more stable than the basic waveform based on a PLL input signal whose frequency is an integer multiple of the basic frequency or a reciprocal of an integer multiple thereof, a first sampling unit for outputting a first sampling signal which results from sampling the first basic waveform with the sampling clock, and an output unit for outputting the timing signal based on the first sampling signal.
