Abstract:
A semiconductor integrated circuit comprising:a first circuit having an output terminal; a second circuit having an input terminal; and an interconnect for connecting the output terminal of the first circuit and the input terminal of the second circuit, a characteristic impedance of the interconnect matching one of (1) output and/or input impedance of the first circuit, (2) an input impedance of the second circuit, and (3) an output impedance of the first circuit and an input impedance of the second circuit, in a predetermined frequency range, wherein the characteristic impedance of the interconnect is determined so that an eye opening ratio representing a rate of an amplitude size of an eye pattern of a data signal propagating in the interconnect to the amplitude size of the eye pattern of the data signal input may be larger than the predetermined value.
