Patent Number: 7,612,631

Title: Motherboard

Abstract: A motherboard includes a signal control chip, a signal switch chip connected to the signal control chip via a plurality of first transmission lines, and a complex connector configured for connecting to a first type of transmission device or a second type of transmission device. The signal control chip is connected to the complex connector via the first transmission lines and a plurality of second transmission lines. The signal switch chip is electrically connected to the complex connector via a plurality of third transmission lines. Each second transmission line is connected in series with a first resistor. Each third transmission line is connected in series with a second resistor. When the first type of transmission device is mounted on the complex connector, the signal switch chip and the second resistors are removed. When the second type of transmission device is mounted on the complex connector, the first resistors are removed.
