<P>PROBLEM TO BE SOLVED: To provide a jitter generation circuit that does not require an analog circuit, reduces circuit size, and can reduce power consumption. <P>SOLUTION: The jitter generation circuit comprises signal wiring P1 to which a clock signal, where a jitter component is added, is transmitted; an input buffer 10 provided at the input side of the signal wiring P1; an output buffer 30 provided at the output side of the signal wiring P1; signal wiring P2 closely arranged to the signal wiring P1; and a jitter generation signal output section 20 for inputting a jitter generation signal in synchronization with the clock signal inputted to the signal wiring P1 to the signal wiring P2. As the jitter generation signal, for example a pseudo random bit string signal is used. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
