<P>PROBLEM TO BE SOLVED: To provide a radio communication apparatus that can recover from an asynchronous state to a synchronous state early in a configuration of synchronization with a target device in accordance with a signal from the target device. <P>SOLUTION: A radio communication apparatus 201 includes: a jitter suppression section 12 for generating a first control voltage based on a reproduced timing signal generated according to received data received from a target device, and supplying the first control voltage to a voltage-controlled oscillator 25 to generate a reference timing signal having frequency components in which predetermined and higher frequency components of the frequency components of the reproduced timing signal are attenuated, and synchronized with the reproduced timing signal; and an oscillator control section 13 for detecting an anomaly in the reproduced timing signal generated by a timing signal generation section 22, and if detecting an anomaly, supplying a second control voltage that is a voltage within a first predetermined range to the voltage-controlled oscillator 25 in place of the first control voltage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
