    摘要: A method which provides a very simple way of forming a control signal if the frequencies differ too greatly from one another between a useful signal and a reference signal. A control signal is produced which indicates that the frequency error between the frequencies of a useful signal and the frequency of a reference signal exceeds a prescribed error limit value, where the useful signal and the reference signal are used to produce a pulsed signal whose pulse length is proportional to the frequency difference between the useful signal and the reference signal. The pulse length is then compared with a prescribed maximum pulse length, and the control signal is produced if the pulse length exceeds the prescribed maximum pulse length.

    摘要: A receiver circuit is disclosed which enables a reception signal fed into the receiver circuit by a reception element to be processed—e.g. amplified—with little to no errors The receiver circuit has a cascode circuit on an input side, which cascode circuit generates an output signal from the reception signal of the reception element. Control means that act on the cascode circuit are connected to the cascode circuit. The control means are configured in such a way that they counteract an increase in a high level of the output signal of the cascode circuit on account of an excessively large input signal from of the reception element.

    摘要: According to the invention, a duty cycle correction device is disclosed. The duty cycle correction device corrects the duty cycle value of a data signal as a function of a digital control signal that is applied to a control input of the duty cycle correction device, and forms a corrected data signal at a signal output. The circuit has a digital duty cycle detector that is connected to the signal output and to the control input of the duty cycle correction device. The circuit determines the actual duty cycle value of the corrected data signal, and produces the digital control signal for the duty cycle correction device such that the discrepancy between the respective actual duty cycle value and a predetermined duty cycle value is a minimum. The duty cycle detector contains a digital integrator for forming the control signal.

    摘要: The invention relates to a circuit arrangement for operating a laser diode, having: a laser driver, to which a differential input signal is applied and which provides a differential output signal comprising a first output signal and a second output signal that is the inverse of the first output signal, which are provided at a first and a second laser driver output; a first laser diode, which is connected to the first laser driver output and to which the first output signal is applied; and a second laser diode, which is connected to the second laser driver output and to which the second output signal is applied. In this case, the load provided at the first laser driver output and the load provided at the second laser driver output are essentially identical. This has the effect that the supply current of the laser driver is essentially constant and, therefore, a high-frequency interference signal that effects an interference emission is not applied to said supply current. Only the light of a laser diode is utilized for information transmission.
