IPC: H04J3/07
Filed: 1988-03-18
Abstract: PURPOSE:To simplify the hardware constitution by using a stuff/destuff clock generated from a clock control circuit so as to reproduce the same clock as the sender side. CONSTITUTION:The stuff/destuff clock outputted from a control circuit 12 is frequency-divided by a counter circuit 2 at a prescribed ratio. Then the clock subject to frequency division is applied with phase look by the circuit 3 so that the clock has the same frequency as that of the sampling frequency at the sender side. Thus, the same clock as tie sender side is recovered without requiring frequency information and it is used as a readout clock for a buffer memory 14.
