Title: Clock recovery circuit
Inventor: ARAI TOSHIAKI
IPC: H04L7/027
Filed: 1990-10-31
Abstract: PURPOSE:To realize a clock recovery circuit to prevent production of jitter by connecting a buffer amplifier section of a low output impedance and a high input impedance between a tuning amplifier section and a waveform shaping section. CONSTITUTION:A clock recovery signal from an input terminal 1 is inputted to a tuning amplifier section 2 and its sinusoidal output is inputted to a buffer amplifier section 3 through a coupling resistor R1. Then the signal is shaped into a rectangular wave by a waveform shaping section 4 and outputted as a recovered clock signal from an output terminal 5. In this case, a bias voltage is impressed to the amplifier section 3 by using a bias resistor R2 to control its output DC level and to adjust an input DC bias quantity of the waveform shaping section 4 thereby adjusting the duty ratio of a clock signal at the terminal 5 to be 50%. As a result, even when the input impedance of the shaping section 4 of a logic IC is fluctuated by a voltage, the appearance of the result of fluctuation at the input of the amplifier section 3 is prevented. Thus, production of distortion in the sinusoidal wave from the amplifier section 2 is prevented and jitter of a recovered clock signal is improved.
