The apparatus for generating a downlink low speed coupled control channel strobe signal of a personal communication terminal capable of generating a strobe signal for a downlink low speed coupled control channel (SACCH) for a data link based on a 13 MHｚ clock signal. A corresponding bit synchronization signal is generated, and a time slot synchronization signal having a period of 156.25 bits is generated using the bit synchronization signal and the clock signal, and the count value of the time slot synchronization signal and the reference time slot number are identical. The time slot strobe signal for data transmission and reception When the frame synchronization signal is generated using the time slot number generated according to the count of the LOT synchronization signal, and the frame synchronization signal is generated by counting the frame synchronization signal, the low speed combined control channel number assigned to eight subscribers is also generated. A time slot strobe signal corresponding to a period in which both data values coincide with the frame number after outputting the selection signal for the 51-multi frame, which is a reference, is generated and compared with the frame number. By outputting the signal based on the selection signal, a low speed combined control channel strobe signal for data transmission and reception for eight subscribers is generated.
