摘要： A semiconductor device (200) comprising an interface logic module (220) for transmitting data frames across an interface (215), and controller logic module (210) arranged to control a rate at which the interface logic (220) transmits data across the interface (215). Upon receipt of data frames to transmit across the interface (215), the controller logic module (210) is arranged to determine a sequence of data rates with which to transmit sequential data frames across the interface (215), and to configure the transmission of the data frames across the interface (215) according to the determined data rate sequence. The selection of these data rates will be dependent on specific critical RF frequencies where EMI impacts have to be minimised.
