<p>PROBLEM TO BE SOLVED: To keep the synchronization precision in the standby state and to save the power consumption. SOLUTION: A control circuit 9 applies power supply control or the like to each circuit such as a synchronization correction signal generating circuit 4, a PN code generator 6 and an information decoding circuit 8 in each independent timing. The control circuit 9 controls driving the information decoding circuit 8 once for N times of driving each circuit such as the synchronization correction signal generating circuit 4 synchronously with the timing of driving each circuit such as the synchronization correction signal generating circuit 4.</p> |
