A data transmission system and an automatic delay value acquisition method. For an interface to be tested, an AD chip determines a first delay test value of a clock line relative to a data line on the basis of a preset delay set, sends first test data to an SOC chip by means of the data line, uses a delay-locked loop module to generate a clock signal on the basis of the first delay test value, and sends the clock signal to the SOC chip by means of the clock line; the SOC chip receives, on the basis of the clock signal, the first test data sent by the AD chip to obtain second test data, and returns the second test data to the AD chip; the AD chip compares the received test data with the first test data sent by the AD chip, and when the received test data and the first test data are the same, determines that the first delay test value is a target delay test value. In this way, when using the AD chip, the delay value of the clock line relative to the data line can be automatically determined, and because the delay value is obtained by automatic testing conducted by the device, the test efficiency is significantly enhanced, and the test accuracy is improved.
