Abstract
An integrated circuit component receives an input signal via an external signal conduction path during a first interval and transmits an output signal via the external signal conduction path during a second interval. The integrated circuit component terminates the input signal and the output signal within one or more termination elements having an impedance in accordance with a characteristic impedance of the external signal conduction path to obviate signal termination within another integrated circuit component to which the output signal is destined and from which the input signal is sourced.
Claims21
A first integrated circuit component comprising:
