Abstract:
A transmitter configured for pre-emphasis is described. The transmitter includes a voltage-driven single-ended-termination driver circuitry. The voltage-driven single-ended-termination driver circuitry includes a first termination point and a second termination point. The transmitter also includes a pre-emphasis encoder circuitry. The pre-emphasis encoder circuitry receives a pre-emphasis signal. The transmitter may reduce signal loss in transmission lines by detecting a transition in a data stream, adjusting a source determination resistance and obtaining a gain from the adjusted source determination resistance.
