    摘要: A receiver is provided capable of receiving both RDS (Radio Data System) and DARC (DAta Radio Channel) system FM multiplex broadcasting. An RDS signal demodulating circuit is provided with a PLL circuit which comprising a first frequency divider for dividing an output of a crystal oscillator, a phase comparator for inputting an output of the first frequency divider, a low-pass filter connected with the phase comparator, a VCO connected with the low-pass filter, and a second frequency divider for dividing an output of the VOC and outputting the divided output signal to the phase comparator. An output of the VCO is transmitted as a reference clock RDSCL for demodulation of an RDS signal.

    摘要: An offset circuit (2) detects an offset word serving as a synchronization pattern. By being triggered by the detection, main and subordinate synchronization detection circuits (5 and 6) detect the periodicity of the offset word only during a predetermined backward guard period. Both synchronization detection circuits (5 and 6) detect offset words at different timings. Therefore, if one synchronization detection circuit (5 or 6) fails in detection of synchronization, it is possible to use a detection result of the other synchronization detection circuit (5 or 6). Moreover, received data during the backward guard period is stored in a data memory (11). Therefore, it is possible to use the stored data as received data after detection of synchronization. Even after establishment of synchronization, the synchronization detection circuit (5 or 6) continuously detects the periodicity of an offset word at a timing different from an established timing. Therefore, when established synchronization is incorrect, it can immediately be corrected.
