<P>PROBLEM TO BE SOLVED: To provide an LSI, for reducing jitter depending on a data pattern by using a receiver of an interface, which is capable of automatically adjusting setting of a delay amount for reduction. <P>SOLUTION: In a semiconductor device, since a previous state of data pattern dependent jitter is predictable, a state of data received by a receiver is held and timing to capture input data is adjusted from the held state and from input data. As an adjustment mechanism inside the receiver for determining a delay amount depending on a mounting form, pulse data at intervals of one cycle and pulse data at intervals of two cycles are transmitted/received from a driver as a test pattern. An automatic adjustment mechanism for determining a delay amount optimal for a system from a rising and falling time difference of pulses having different pulse widths, is provided. <P>COPYRIGHT: (C)2010,JPO&INPIT |
