ABSTRACT:
The present invention relates to an apparatus and method for providing synchronization of an output signal to a synchronization information. The synchronization is accomplished by providing coupling of a correction control information that controls a signal generating means, e.g. a phase locked loop arrangement (30) or a direct digital synthesis arrangement, to its exact frequency to a frequency conversion unit (90) that converts an uncorrected reference frequency to a correct or exact reference frequency. Thereby, the uncorrected reference frequency for the signal generating means (30) can be provided by a simple crystal oscillator (2) without any means for frequency control. The setting of the signal generating means (30) and the frequency conversion unit (90) can be done in a predetermined sequence which enables a user equipment to synchronize its reference frequency to the synchronization information emitted by a communication network.
