ABSTRACT:
A radio selective calling receiver which can improve the precision of a timepiece up to the clock precision of a reception signal from a base station is provided. A bit synchronization section establishes bit synchronization of a digital signal from a reception section to output a reproduction clock. A frequency divider for a timepiece function frequency-divides a reference clock with insufficient precision, which is supplied from a reference clock generation section, by a fixed value while the digital signal is in a frame step-out state. While the digital signal is in a frame synchronized state, the frequency divider variably frequency-divides the reference clock by using a phase correction signal for correcting an internal phase advance/delay, which is output from the bit synchronization section, thereby correcting a gain/loss in time displayed on a display section.
