<p>PROBLEM TO BE SOLVED: To convert an input frame into a frame at a different speed and to output the converted frame with a simple circuit configuration, independently of the difference in speed between the input and output frames. SOLUTION: When converting an input frame into a high-speed output frame, for example, a phase comparator circuit 5 compares the phase of a low speed frame pulse from a timing generating circuit 4 with the phase of an output timing from a timing generating circuit 6, to select either of biphase latch timing signals from the circuit 4. A transfer circuit 2 latches an input frame converted into parallel data from a demultiplexer circuit 1, and a multiplexer circuit 3 outputs the input frame data that are multiplexed on other 8-bit parallel data on the basis of the output timing.</p> |
