Abstract
A circuit arrangement comprising a matrix-shaped memory for variable delay digital signals comprises a selection device for selecting columns of the memory, the selection device being switchable between two selected neighboring columns into which a portion of an external delay time setting data word is supplied for the selection of the columns. A dynamic switching by way of a supplied control signal is provided for switching between two neighboring columns. A setting and control device receives the full external delay time setting data word supplied thereto and generates a reset signal for the memory and a control signal for the selection device, and is supplied with an external reset signal by way of a reset input to directly reset the setting and control device and to indirectly reset the memory. The memory comprises a data input by way of which the data signal to be delayed can be input. The selection device comprises a data output by way of which the delayed data signals can be output. The selection device has data inputs connected to data outputs of the memory and the setting and control device is a data clock controlled device.
