Apparatus for generating synchronized clock signals, elec-tronic system, base station and mobile device

An apparatus for generating synchronized clock signals, comprising:

• a first circuit comprising a clock divider circuit configured to receive a first clock signal and to generate a second clock signal by frequency dividing the first clock signal;
• and
• one or more second circuits each comprising a respective synchronization circuit configured to receive the first clock signal,
• wherein the synchronization circuit of one of the one or more second circuits is configured to receive the second clock signal from the first circuit and to resample the second clock signal based on the first clock signal in order to generate a replica of the second clock signal that is in phase with the second clock signal,
• wherein the apparatus comprises a plurality of second circuits forming a series of second circuits, wherein the one second circuit configured to receive the second clock signal from the first circuit is the first one of the series of second circuits, and wherein the synchronization circuits of the other ones of the series of second circuits are configured to receive the respective replica of the second clock signal generated by the respective preceding second circuit in the series of second circuits and to resample the respectively received replica of the second clock signal based on the first clock signal in order to generate a respective replica of the second clock signal that is in phase with the second clock signal,
• wherein the first circuit further comprises a second clock divider circuit configured to receive the second clock signal and to generate a third clock signal by frequency dividing the second clock signal.
