摘要
A device for receiving an RF input signal (2) and for processing the received RF input signal (2) is provided. The device comprises: an input (3) receiving the RF input signal (2); a clock circuit (34) generating a reference clock signal having a clock circuit specific reference frequency (fclock); and a frequency feedback control loop (17, 18, 20, 21, 22, 23; 35, 37, 38). The frequency feedback control loop is adapted to extract frequency information from the RF input signal (2), to put the clock circuit specific reference frequency (fclock) into relation with the extracted frequency information and to correct for inaccuracies of the clock circuit specific reference frequency based on this relation.
