Abstract
PURPOSE:To perform control which sends out a control signal in basic frame units as many times as the number of transponders by providing a TDMA basic frame counter to an address converting circuit provided externally to a control LSI which controls the control signal. CONSTITUTION:The control LSI 1 for a satellite communication TDMA device has a burst counter 8 and processing is performed, burst by burst, to control the transmission of the control signal, etc. A basic frame counter 6 counts basic frames of TDMA. A buffer 2 holds the control signal. The control LSI 1 access the high-order bits of the buffer 2 with the output of the basic frame counter 6 and also accesses the low-order bits of the buffer 2 with the output of the basic frame counter 6 to perform the control where in the control signal held in the buffer 2 is sent out in basic frame units as many times as the number of transponders. Consequently, the control signal is sent out as many times as the number of the transponders without increasing the circuit scale.
