Abstract:
A method for internal synchronization of a first and at least a second module which are within a single telecommunication device, and each of which has a clock generator, the method comprising the steps oftransmitting, by the first module, a first clock signal generated by its clock generator to the at least one second module, synchronizing the clock generator of the at least one second module with the first clock signal, transmitting, by the at least one second module, a second clock signal, generated by its clock generator, that is synchronized with the first clock signal to the first module, determining, by the first module, a first time difference value between the first clock signal and the at least one second clock signal, which time difference value is essentially due to the transmission time of the first and the at least one second clock signal between the first and the at least one second module, transmitting, by the first module, an item of information about the first time difference value to the at least one second module, and adjusting the clock generator of the at least one second module on the basis of the information about the first time difference value so that said first and second clock signals are synchronous, wherein the first time difference value is halved to adjust the clock generator of the at least one second module.
