Abstract:
A reduced power differential type termination circuit for use in SSTL, HSTL and other transmission line systems reduces power consumption. A differential type termination circuit may comprise first and second nodes for coupling, respectively, to first and second transmission lines; a first impedance coupled between the first transmission line and a third node; a second impedance coupled between the second transmission line and the third node; and a low direct current reference voltage generator for generating a reference voltage applied to the third node. The first and second transmission lines may transmit complimentary signals. The first and second impedances may be symmetric or asymmetric. The first impedance may match the second impedance. The first and second impedances may, respectively, match the impedances of the first and second transmission lines. The first and/or second impedances may include a bidirectional switch, such as a transmission gate, to enable and disable the termination circuit.
