    • A test enable signal Data_En is output from a data generator 11 in a tester 10 to a device under a test (DUT) 20. In the DUT 20, a first logic circuit 21 converts a signal pattern with an ordinary transfer rate, which has been stored on a register 28, into a high-transfer-rate signal pattern SpeedData_Tx with a high rate. And a transmitter 22 transmits the high-transfer-rate signal. During a test, the high-transfer-rate signal transmitted is received by, a receiver 23 with a switch 24 turned ON. Then, the high-transfer-rate signal received is output to a second logic circuit 26, which converts the high-transfer-rate signal into a low-transfer-rate signal Data_Rx with an ordinary rate. Finally, the low-transfer-rate signal is output to the tester 10 and compared to an expected value thereof by a comparator 12. In this manner, a semiconductor device operating at a high speed can be tested using a tester operating at a lower speed.

    • A reproducer for reproducing a binary digital data signal from a signal received at a receiver side. A pulse train is detected from the received signal at a pulse detector. Each pulse in the pulse train sets a first D-type flip-flop, which is, in turn, cleared by a clear pulse produced by a second D-type flip-flop in response to a clock pulse just after the first D-type flip-flop is set. The output of the first D-type flip-flop is applied to a data input terminal of a third D-type flip-flop and is taken into the third D-type flip-flop by the same clock pulse. The clock pulse repetition frequency is synchronous with the binary digital data signal. Thus, the reproduced binary digital data signal is obtained on an output of the third D-type flip-flop.
