Abstract
A circuit for synchronizing signals during an exchange of information between circuits, in particular between computer chips, of a system of circuits, is described. The configuration has a delay locked loop (DLL) circuit for synchronizing an internal clock between a respective circuit and an external clock of the circuit system according to the phase difference between the two clocks in a manner dependent on phase changes in the signals. A response sensitivity of the DLL circuit is defined by a filter, which enables a renewed synchronization only after the arrival of a plurality of phase change events. The filter provided for setting the response sensitivity of the DLL circuit is of a variable configuration.
