Abstract:
A digital communication system, comprising:first and second communication devices coupled to opposite ends of a transmission line and operating in response to a periodic clock signal, wherein the first and second communication devices are configured to simultaneously: (i) drive an output data signal upon the transmission line during a first portion of a period of the clock signal, and (ii) receive an input signal from the transmission line during a remainder of the period of the clock signal; wherein the first and second communication devices each include an input/output driver circuit comprising: an input/output node coupled to the transmission line; and an output driver coupled to the input/output node, wherein the output driver is configured to drive the output signal upon the input/output node during the first portion of the period of the clock signal, and is further configured to resistively terminate the transmission line during a second portion of the period of the clock signal.
