Abstract: A wireless communication device comprises a number of sub-systems operably coupled to a data interface for routeing data between the number of sub-systems. A clock generation function generates a clock signal substantially at a data transfer rate to be used over the data interface whereby the clock signal is generated at a rate that minimises harmonic content of the clock signal at operational frequencies of the wireless communication device. Thus, a suitable data rate is selected and supported by the data interface that accommodates the desired bandwidth, clock rate and/or chip rate of the functional elements that are coupled by the data interface within the wireless communication device, whilst minimising the effects of harmonic interference from the clock signal(s).
