    摘要: A memory arrangement comprises a first memory module and a second memory module. An item of information to be written to the memory arrangement is written with a first address both to the first memory module and to the second memory module. When reading, the item of information is read either from the first memory module by means of the first address or from the second memory module by means of a second address differing from the first address. Subsequently a check is made as to whether the item of information is defective. If this is the case, the item of information is read from the respective other memory module.

    摘要: A Phase shifter for generating a phase-shifted, in particular phase-delayed, output signal from an input signal is disclosed. In one embodiment, the phase shifter includes a first delay line and at least one further delay line with respectively cascaded delay elements that form a U-shaped signal path along which at least one delay element is adapted to be controlled to be optionally opening or closing. A phase discriminator located at the input side of which a clock signal and a signal from one of the delay lines can be applied, and the output side of which is connected with a respective control input of the delay elements. The clock signal can also be applied to the first delay line, so that a feedback loop is formed by the phase discriminator and at least one of the delay lines. The input signal can be applied to the delay line whose signal output is not connected with the phase discriminator, and the output signal can be output therefrom.

    摘要: A digitally controlled circuit for reducing the phase modulation of a signal. The circuit has a multiphase clock generator that produces n phases of a clock that is m-times the signal. The circuit further has a multiplexer with n inputs for the n phases of the clock and with one output which supplies the output signal. The output signal and the signal are connected to the inputs of a phase comparator. The output signal of the comparator is supplied to a sigma-delta modulator whose output signals are used for controlling the multiplexer. A jittered input signal is compared in the phase comparator with a master clock. The determined phase difference is integrated in a sigma-delta modulator. The aim of the circuit is to generate a clock without jitter, digitally and without using external components. This circuit provides 20 dB/decade attenuation of the jitter received in the SYNC signal, based on the P-regulator characteristic.

    摘要: In a transceiver which is configured in particular for transmitting optical data, there is provided a device for reconstructing data from a received data signal (RX), having a clock-signal recovery unit (3) for recovering a clock signal belonging to the transmitted data from the received data signal, and having a data reconstruction unit (2) for reconstructing the transmitted data from the received data signal using the recovered clock signal (fCLK), and for emitting a data stream (DATA) which is synchronised with the recovered clock signal. A detector unit (9) detects an error state in the received data signal (RX) which prevents the data from being reconstructed reliably, switching means having a digital phase-locked lock (13) being provided to enable a signal having a clock rate which corresponds to the mean value of the clock signal (fCLK) previously recovered by the clock-signal recovery unit (3) to be fed, as a reference signal, to a phase-locked loop of the clock-signal recovery unit (3) in this event in place of the received data signal, thus ensuring that the phase-locked loop of the clock-signal recovery unit (3) will continue to oscillate properly even in this event.
