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.
Claims20
A data communication system comprising:
- a data transmitting device that transmits a test pattern;
- and
- a data receiving device that receives the test pattern, wherein
- the data receiving device includes a communication interface that changes more than once a threshold for determining whether received data is High or Low during receiving the test pattern, and
- the communication interface includes:
- a comparison circuit that compares the test pattern in which determination of High or Low is made on a basis of the threshold that has been changed more than once to an expected value;
- and
- a selection circuit that selects the threshold based on the result of comparison between the test pattern and the expected value.
