Abstract: An arrangement for generating a transmission clock signal and a reception clock signal is proposed in which only a single voltage-controlled oscillator is used, the reception clock signal being generated by phase-adjusting means whereas the transmission clock signal is generated directly by the voltage-controlled oscillator. Cross-talk between a plurality of voltage-controlled oscillators can be prevented in this way. Also, various measures are proposed for optimizing a circuit of this kind.

Abstract: An integrated circuit includes a memory interface circuit. The memory interface circuit includes a first interface channel configured to couple to at least one memory device, a second interface channel configured to couple to at least one memory device, and a multiplexer configured to select between the first interface channel and the second interface channel.

Abstract: The invention relates to an output circuit for a hub chip and a method for actuating an output circuit for outputting a high-frequency differential output signal between a first and a second output node, having a differential amplifier unit which comprises a first switching device and a first terminating resistor which are connected in series between a high supply potential and a low supply potential and between which the first output node is provided, and a second switching device and a second terminating resistor which are connected in series between the high supply potential and the low supply potential and between which the second output node is provided. A control unit opens one of the first and second switching devices and closes the respective other one when there is a level change to be made in the output signal, such that the switching device which is to be opened is switched at a time before the other switching device, which is to be closed.

Abstract: The invention relates to a compensation circuit for driver circuits having a current reference source which generates at least one reference signal which is modulated with respect to an input signal, having a current-comparison source which generates at least one comparison signal which is modulated with respect to the input signal, the modulated comparison signals having an inverse characteristic to that of the modulated reference signals in respect of the parameters to be modulated, having a comparison unit to which the modulated reference signals and the modulated comparison signals are fed and which generates from a comparison of these modulated modulating signals at least one digital output signal which can be fed to driver circuits connected downstream.
