Abstract:
1. An electronic device, comprising: a plurality of semiconductor devices configured to be connected to a signal source in a daisy chain; a first wire line configured to connect from the signal source to branch points in the daisy chain, and to connect between selected ones of the branch points; second wire lines configured to connect the branch points and input terminals of the semiconductor devices corresponding to the branch points, respectively; and terminal circuits configured to be connected between the second wire lines and the input terminals of the semiconductor devices, and to suppress reflected wave based on signal reflection of the semiconductor devices, wherein impedance of one of the second wire lines is higher than one of impedance of the first wire line, impedance of a wire line in a package including the semiconductor devices, and direct-current impedance of a resistance component included by the terminal circuits.
