Driver/receiver circuitry for enhanced PCI with differential signaling

A system of supporting differential signaling circuitry in an enhanced PCI bus within a data processing system is disclosed. The enhanced PCI bus comprises a plurality of differential signal conductor pairs, has been disclosed. A system and method in accordance with the present invention comprises a system for providing each of the plurality of differential signal pairs over a first line and a second line, the first line having a front end and a back end, the second line having a front end and a back end. The system and method includes a differential driver for driving the first line and the second line with a small voltage change of equal amounts in opposite direction to change logic states, a receiver for sensing a voltage change between the first line and the second line and a termination network coupled to the first line and second line for terminating the first line and the second line. According to the system and method disclosed herein, the present invention provides for higher frequency capability and lower noise to signal ratio, thereby allowing an increase in overall system performance.
