Semiconductor integrated circuit apparatus

摘要

A semiconductor integrated circuit apparatus that is capable of reducing crosstalk without increasing the number of low impedance external terminals is realized by implementing first external terminals that are adapted to input/output high frequency signals of various channels (e.g. D-terminal), a second external terminal that has a higher impedance than the first external terminals and is implemented between two of the first external terminals, and a capacitor of which one end is connected to the second external terminal and the other end is arranged to have a predetermined electrical potential.
