Abstract
PURPOSE:To prevent the instability of operation by synchronizing a timing generating circuit by an external identifying signal, when a frame synchronizing signal is not contained in an input signal. CONSTITUTION:When the frame synchronizing signal 22 is not contained in input data 19, a synchronizing signal generation circuit 2 outputs the synchronizing signal 23 at every trailing edge of a channel selecting signal 21. If synchronization is attained once by one of the channel selecting signals 21, the head of a frame can be synchronized. Besides, when the frame synchronizing signal does not exist, the head of the frame can be synchronized with an external frame signal by inputting the external frame signal 26 which has the same frame period as the timing generating circuit 4, from an external frame signal input terminal 17.
