摘要： Process for controlling the switching of the data rate at a digital interface exchanging data and control messages between a Radio Frequency (RF) circuit and a digital circuit, comprising the steps of: setting by default the data rate to a low speed (LS) rate having a density presenting a first lobe being inferior to the frequency band considered in said RF circuit so as to prevent desensitization of the LNAs by the noise produced by said digital interface; storing the data and control messages message into a FIFO and monitoring the level of said FIFO; whenever the level of said FIFO reaches a predetermined threshold value, then controlling said interface to switch to a second high speed (HS) rate in order to flush said FIFO. In one embodiment, the LS frequency is set to a value of 832 MHz, thus preventing simultaneously desensitization of the GSM band and also the GPS band.
