A data receiver device includes a logic unit configured to generate a test pattern signal, receive a test result signal in the test mode, and compare the test pattern signal with the test result signal to perform a test in the test mode. The data receiver further includes a system frequency control circuit configured to multiply a reference clock signal by a multiplication factor received from the logic unit and to output a test clock signal, an output terminal configured to serialize the test pattern signal based on the test clock signal and to output an output signal, and an input terminal configured to recover a data signal and a data clock signal from an input signal based on the output signal, to deserialize the data signal based on the data clock signal, and to output the test result signal to the logic unit. |
