A delay device, with a controllable delay time, has three circuit parts. The delay device is connected in series between an input connection for receiving an input clock signal and an output connection for outputting an output clock signal. The delay time is set based on a phase difference between the input clock signal and the output clock signal. The first circuit part reduces the frequency of the input clock signal and forwards a clock signal with a reduced frequency. The second circuit part delays the signal and forwards it to the third circuit part which uses the modified clock signal to generate the output clock signal which has a frequency matching that of the input clock signal. Since a low-frequency clock signal is processed in the second circuit part, problems relating to a signal change in a high-frequency input clock signal in a delay chain are avoided.
