  • Patent number: 10983164
    Abstract: A test apparatus may include transceivers and a global de-skew circuit. In a training mode, the transceivers provide first timing information obtained by delaying a first data signal in the range of up to a preset unit interval based on a clock signal and receive second timing information corresponding to timing differences between a slowest transceiver and the remaining transceivers. In an operation mode, the transceivers provide compensation data to a plurality of DUTs (Devices Under Test) substantially simultaneously. The compensation data may be obtained by delaying a second data signal by multiples of the preset unit interval in response to the second timing information. In the training mode, the global de-skew circuit receives the first timing information, calculates, using the first timing information, the timing differences between the slowest transceiver and the remaining transceivers, and provides the second timing information corresponding to the timing differences to the transceivers.
