Test data generator for generating test data patterns for the testing of a circuit having a frequency multiplication circuit, which increases a low clock frequency of an input clock signal received by a test unit with a specific clock frequency multiplication factor. Also provided is a plurality of data registers for storing test data words read from the data registers, and multiplexer that switches through a test data word read from a data register with the high clock frequency of the output clock signal to a data bus in a way dependent on a register selection control datum of a multi-position register selection control data vector.
