ABSTRACT:
A transmission line adapter for high speed interface. A receiver receives input signals via a transmission line. An active termination circuit is selectively connected to the transmission line in parallel with the receiver according to a receive condition. A self-terminated driver circuit outputs a first voltage and a second voltage according to output data. A selective circuit for selectively connects the self-terminated driver circuit to the transmission line when output of the self-terminated driver circuit is a first voltage, and selectively connects the self-terminated driver circuit or the active termination circuit to the transmission line when the output is a second voltage.
