Abstract

To be able to use a clock generation unit (2) for different mobile radio systems, the clock generation unit (2) which includes a phase-locked loop (4) for converting a reference clock (fR) into a working clock is provided and includes circuit portions (16a, 16b; 20a, 20b) which are designed for different reference clocks (fR) while a respective one of the circuit portions (16a, 20a) to which a special reference clock (fR) is assigned can be selected. The clock generation unit (2) can thus be operated with different reference clocks of different mobile radio systems.
