ABSTRACT:
An integrated circuit and a method for tuning an internal clock signal with respect to data that is to be emitted includes an adjustment circuit with a compensating circuit for synchronizing the internal clock signal with respect to the data that is to be emitted. Setting data, which is dependent on first adjustment data and on second adjustment data, is applied to the compensating circuit. The first adjustment data is determined using a tuning method during the front-end test, and is stored in a read only memory. The second adjustment data is determined in a fine-tuning method in the finished manufactured component, and is stored in a read/write memory.
