Filed: 1987-06-09
Abstract: PURPOSE:To extract stably a clock even when any other pulse pattern signal comes by providing a zero cross detection circuit detecting the inversion of a positive/negative voltage and a tuning circuit for a transmission signal. CONSTITUTION:An input signal is amplified by an amplifier section 21, given to a 1.544MHz tuning section 22 and a sinusoidal wave of 1.544MHz is fed to a zero cross detection section 23. A comparator of the detection section 23 detects a point of time when the signal changes from a positive to a signal negative signal or from a negative signal to a positive signal and applies amplitude limit. The detection output is sent to a timing generation section. Moreover, an input signal interruption detecting circuit 24 is a circuit to prevent malfunction due to noise if the input signal is lost. Since the zero cross detection circuit is used in place of a PLL circuit and a limiter, the possibility of the increased timing jitter is precluded and the clock is extracted stably by a simple circuit.
