<p>PURPOSE:To obtain a TDMA transfer synchronizing circuit in which the synchronization of transfer is accurately established with simple constitution and to realize the TDMA equipment having an elastic buffer capable of re-reading with a clock signal without fluctuation with the accurate transfer synchronization. CONSTITUTION:The TDMA transfer synchronizing circuit 24 is provided with a re-timing circuit 31 synchronizing a synchronization word detection signal S5 detected by a burst reception signal S1 with a system clock S4 having a frequency being (n) times of the frequency of the reception signal S1 and with a frequency divider 32 cleared by the synchronization word detection signal S5 subjected to re-timing and applying 1/n frequency division to the system clock S4. The output S6 of the frequency divider 32 is used for a transfer timing signal of its own station. Furthermore, the TDMA equipment is provided with the above-mentioned TDMA transfer synchronizing circuit 24 and an input and output asynchronizing memory 26 in which a burst reception signal is written, and the output of the frequency divider 32 is used for the read clock of the input and output asynchronizing memory 26.</p> |
