Abstract
There is provided a system for the bidirectional synchronous transmission of data between a device (1) to be tested and a testing device (2) with a device (1) to be tested and a testing device (2) which can be connected together by way of an electric transmission line (3) and by way of an electric ground line (4). The two devices (1, 2) are suitable for sending and receiving data synchronously with a predetermined clock frequency and phase as sequences of first and second voltages which respectively represent a first and second value of a bit on the electric transmission line (3). To receive data a receiving device (1, 2) samples a voltage on the electric transmission line (3) at predetermined sampling phases of the clock to identify whether the first or the second voltage is present. To send data a sending device (1, 2) produces sequences of first and second voltages in such a way that the first or the second voltage is present on the electric transmission line (3) at the predetermined sampling phases of the receiving device (1, 2). The clock frequency and phase is predetermined by the device (1) to be tested and the testing device (2) is synchronized to said clock frequency and p…
