摘要：
A data transmission system comprises: a pair of transmission lines connecting a plurality of apparatuses; a bridge termination resistor connected between the transmission lines and having a resistance value matching a differential impedance of the transmission lines; a first switch connecting the bridge termination resistor to the transmission lines when being turned on, and disconnecting the bridge termination resistor from the transmission lines when being turned off; pull-up/down resistors connected between the transmission lines and a fixed voltage node, and having resistance values respectively matching characteristic impedances of the transmission lines, the fixed voltage node being a power supply or a ground; and second switches connecting the pull-up/down resistors between the transmission lines and the fixed voltage node when being turned on, and disconnecting the pull-up/down resistors from the transmission lines when being turned off.
