Abstract
A timing generator as master clock for an electronic circuit includes a coarse code and a plurality of fine codes, has a ring oscillator with an uneven number n of delay elements, each of which has a delay output at which clock signal is present; clock dividers which are connected to the delay outputs and at whose output a clock divider output signal is output; start circuit for generating initialization signal to trigger clock dividers, and clock generator that further processes clock signal and generates a coarse code, and an output at which generated timestamp is output, wherein the fine codes of timestamp are formed from clock divider output signals of the clock dividers, and the coarse code and the fine codes contain redundant information that a time shift of the fine codes relative to the coarse code by at most (n−1)/2 time differences results in a correct timestamp.
