Method, clock generator module and receiver module for synchronizing a receiver module

A clock generator module for synchronizing an output signal of at least one receiver module with an external clock signal comprising:

• a clock generation means for generating at least a first clock signal;
• a transmitting means for transmitting the first clock signal to the at least one receiver module, wherein the transmitting means is designed to transmit at least one item of master-slave status information about the first clock signal;
• and
• a selection means wherein the at least one receiver module selects, as a function of the master-slave status information, the first clock signal or a second clock signal as a master synchronization signal for the synchronization of the output signal of the receiver module with the external clock signal.

A method of internal redundant clock distribution to synchronize an output signal of at least one receiver module with at least one external clock signal, comprising:

• the at least one receiver module receiving at least one external clock signal;
• distributing the external clock signal to at least a first independent clock signal generator module and a second independent clock signal generator module;
• transmitting at least one item of master-slave status information about the first independent clock signal generator module and the second independent clock signal generator module to the at least one receiver module;
• regenerating the external clock signal by the first independent clock signal generator module and the second independent clock signal generator module;
• transmitting the clock signals regenerated by the first independent clock signal generator module and the second independent clock signal generator module to the at least one receiver module;
• selecting, as a function of the item of master-slave status information, at least one of the regenerated clock signals from the first independent clock signal generator module and the second independent clock signal generator module to serve as a master synchronization signal for the synchronization of the output signal of the at least one receiver module with the at least one external clock signal;
• synchronizing the output signal of the at least one receiver module with the at least one regenerated clock signal selected as the master synchronization signal.
