摘要

A clock signal output device for outputting an output clock signal as a function of a receive clock signal and in response to at least two input signals receiving each other in a differential mode comprises a signal processing unit (1) comprising a charge pump, which has a capacitor (11) and a current directing unit (12), an electronic outcoupling switch (1S) having a base for receiving a clock signal and switching means (13) connected to two signal inputs (1A, 1B) for the input signals for switching the capacitor (11) in response to the input signals between the power conversion unit (12) and either one Voltage input terminal (21) or a voltage input opposite pole (22), a clock signal output unit (3) having a clock signal output (3A) at the voltage input terminal (21) and one for interrupting a connection from the voltage input terminal (21) and the clock signal output (3A) the tensioning gas opposite polarity (22) provided electronic clock signal switch (3S), which is coupled with its base to the signal processing unit (1), wherein the power conversion unit (12) between a further voltage input terminal (23) and the Auskopplungsschalter (1S) is connected to the capacitor (11) to establish a monitor voltage between the current directing unit (12) and the voltage input counter pole (22) having a monitor voltage sign which is the sign of one between the voltage input terminal (21) and the other voltage input terminal (23) and the voltage input opposite pole (22) Voltage is opposite, and at the voltage input terminal (21), a higher absolute voltage value than at the other voltage input terminal (23) is provided.
