<p>A precision timing generator (415, figure 4) includes a combiner (412) that provides a timing signal by combining a coarse timing signal (428) and a fine timing signal (429) derived from a phase-shifted sinusoidal signal (508) that has a desired phase shift. The coarse timing generator (404) generates the coarse timing signal from a clock signal (416) and a timing command input (420). The fine timing generator (408) includes a sinusoidal-signal generator (504) that receives the clock signal and generates a sinusoidal signal. The fine timing generator (408) also includes a phase shifter (508) that receives the sinusoidal signal and the timing command (420) input and shifts the phase of the sinusoidal signal based on the timing input to generate the phase shifted sinusoidal signal.</p> |
