To achieve both low costs and high inspection guarantee level in shipping inspection of an LSI equipped with a high-speed interface circuit.
The high-speed interface circuit inspection module comprises a high-speed interface circuit 112 which is mounted on a load board 103 which interfaces with an LSI tester 102, is provided with a circuit for converting a signal speed and can change in transmission/reception properties; a control part 113 which controls the transmission/reception properties of the high-speed interface circuit; a clock generator 111 which generates clocks to be supplied to the high-speed interface circuit; a first connector 110 only for high-speed interface which is connected to the high-speed interface circuit and is provided with a signal port for establishing high-speed signal communications with a circuit to be inspected; and a second connector 109 which is connected to the high-speed interface circuit and LSI tester and is provided with a signal port and a power source port for establishing low-speed signal communications with the high-speed interface circuit.
