<P>PROBLEM TO BE SOLVED: To provide a television receiver capable of preventing deterioration of reception performance due to an interference by a demodulation LSI which is not a reception target while receiving broadcast waves. <P>SOLUTION: The demodulation LSI includes: a satellite operation clock 124; a satellite phase comparator 125 that generates operation clock; a satellite loop filter 126; a satellite VCO 127; and a satellite frequency divider 128. The demodulation LSI and a system LSI116 are connected to each other, and the frequency of the satellite operation clock 124 is changed by giving an operation setting through the system LSI 116. A satellite demodulation section 120, a satellite error correction section 121 and a satellite TS output section 123 operate on the basis of the satellite operation clock 124. Therefore, by giving an instruction to reduce satellite operation clock 124 of the demodulation LSI through the system LSI 116, a demodulation LSI operation clock corresponding to the broadcast wave out of the reception target is also reduced; and thus, the interference thereby is prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
