<p>A method for synthesizing a clock signal, said clock signal being locked to a reference clock signal, said method providing for using a third clock signal, operating at a higher frequency. The method provides the steps of: measuring the reference clock signal (CK_REF) by means of the third clock signal (CK_HIGH), operating at a higher frequency, obtaining a measured value (MES) of the reference clock signal (CK_REF) frequency; comparing the measured value (MES) with a nominal value; obtaining a correction value (CRR) as a function of the measured value (MES) and storing said correction value (CRR); using said correction value (CRR) for driving a digital controlled oscillator (OC) that outputs the synthesized clock signal (CK_SYN). <IMAGE></p> |
