Abstract: According to one embodiment, a data communication system includes: a data transmitting device that transmits a test pattern; and a data receiving device that receives the test pattern. The data receiving device receives the test pattern with every change in a threshold for determining whether received data is High or Low, compares the test pattern to an expected value for the respective changed thresholds, and selects the threshold based on the result of comparison between the test pattern and the expected value.

Abstract: In a system in which the phases of a data clock signal and a data signal differ between at an input and at an output, a semiconductor integrated circuit performs a simple BER test without using external equipment and, at the same time, performs a jitter evaluation required for a margin evaluation.
