ABSTRACT:
A synchronous control device having a memory 101 for storing block data blocked in terms of a pre-set data amount, a clock generating circuit 102 for generating input side clocks which are based on a data rate to be synchronized, and a memory control unit 103 for generating output side clocks C.sub.out responsive to input side clocks C.sub.in from the clock generating circuit 102. The memory 101 stores the block data on the block basis, based on the input side clocks C.sub.in from the clock generating circuit 103, and outputs the stored block data based on the output side clocks C.sub.out from the memory control circuit 103. The memory control circuit 103 detects a difference between the input data volume and the output side data volume in the memory 101 for varying the speed of the output side clocks responsive to the amount of the detected difference so that the output side clocks will be synchronized with the input side clocks C.sub.in from the clock generating circuit 103.
