Patent ID: 8064559

Claim:
An apparatus for clock control in transmission-signal processing devices in mobile radio terminal devices which is compatible with a plurality of different mobile radio standards, comprising: a sampling rate converter, a digital/analog converter and a clock control device, wherein the sampling rate converter converts samples provided in a virtual time frame corresponding to a virtual sampling frequency into samples of a physical sampling pattern or an integer fraction thereof for input into the digital/analog converter, and wherein the sampling rate converter outputs a control signal which the clock control device uses to generate a signal which, on average, has an edge repetition rate which corresponds to the virtual sampling frequency or an integer multiple of the virtual sampling frequency, and wherein the signal generated by using the control signal is formed in the clock control device by gating out edges from a physical operating clock, and wherein the signal formed in the clock control device is configured to control a number of operating clock cycles per unit time to dictate a speed in which modulation data is read from a memory.
