Abstract
A signal transmission system has a plurality of signal lines, a plurality of transmitting circuits, a plurality of receiving circuits, and a timing adjusting circuit. The transmitting circuits are provided for the signal lines. Each of the receiving circuits receives a signal from a corresponding one of the transmitting circuits via the signal lines. The timing adjusting circuit, which is provided at the same side as the transmitting circuits, adjusts signal latch timing for the receiving circuits to optimum timing in accordance with signal skew caused between the signal lines. Therefore, a large-capacity and error free transmission can be performed at high speed using a plurality of signal lines without being affected by skew on each of the signal lines.
