Title: Stuff synchronization circuit
Inventor: HAGI KAZUO
IPC: H04J3/07
Filed: 1992-05-20
Abstract: PURPOSE:To facilitate stuff execution control when a periodic pulse to generate a write/read address for a memory is a burst missing period pulse in the stuff synchronization circuit used for a multiplex converter for a PCM transmitter. CONSTITUTION:An up-down counter 5 detects a phase difference between write address generating pulse #1 of an ES memory 1 and a read address generating pulse #2. A stuff execution circuit 4 samples and holds the content of the counter 5 for a prescribed period (missing period T of the pulse #2) and inserts/deletes the pulse #2 in response to a designated value when the content is other than the designated value to implement stuff control. Since the phase difference of the write read address of the ES memory 1 is detected for each prescribed period to implement stuff execution control in this way, the criterion of phase difference detection is made clear and the control is facilitated.
