    摘要: The invention relates to a clock generator comprised of a system clock input (2) for applying a high-frequency system clock signal, of a digital input (3) for applying a settable digital increment value, of an adder (6) for adding the increment value with the feedback digital cumulative value of the adder, of an output register (13) for outputting the highest-order data bit of the digital cumulative value as an output clock signal of the clock generator (1) over an output clock line, and of a digital phase deviation calculating unit (30) for calculating the phase deviation of the output clock signal according to the remaining low-order data bits of the digital cumulative value and of the digital increment value, whereby the phase deviation is output as a digital phase deviation value to a digital data output (29).

    摘要: In order to generate a clock signal (fT1) that is coupled to a reference signal (FBAS), especially to an analog video signal, a free-running clock pulse (fT1) is generated from a high-frequency clock pulse (f0) and the reference signal (FBAS) is digitized therewith. In addition, a second clock pulse (fT1) is generated from the high-frequency clock pulse (f0) and the phase deviation between the first clock pulse (fT2) and the second clock pulse (fT1) is determined. The digitized sampling values of the reference signal (FBAS) at the first clock frequency (fT1) are converted, according to the phase deviation determined, into corresponding digitized sampling values having the second clock frequency (fT1) and are used as a target specification for generating the second clock pulse (fT1) thus coupled to the reference signal.
