A low speed coupled control channel strobe signal generator in downlink of a personal communication terminal capable of generating a strobe signal for a css-c-ss-c-ss-c, which is based on a clock of 13MHｚ, has a length of 48 clocks. In addition, in the personal communication system configured to configure one time slot with 156.25 bits, a reference clock of 13 MHz is generated to generate a bit synchronization signal based on the reference clock and the frame start signal, and then the bit synchronization signal and the reference signal. Time slot synchronization based on clock A is generated. Subsequently, the time slot synchronization signal is counted to calculate the current time slot number, and the strobe signal corresponding to the assigned time slot is output based on the time slot number and the time slot number assigned from the outside. Then, a frame synchronization signal is generated based on the timeslot number, the frame synchronization signal is counted to calculate a frame number, and 12 or 25 reference data are generated to compare the reference data with the frame number, and then both data. The low speed coupled control channel strobe signal can be generated by outputting the timeslot strobe signal corresponding to the period in which the values coincide.
