High speed signaling system with adaptive transmit pre-emphasis, reflection cancellation and offset cancellation

摘要

A method of operation an integrated circuit device, the method comprising:
incrementally adjusting a plurality of drive strength values used to control signal levels generated by a corresponding plurality of output drivers (205) included within a transmit circuit (201) the adjusted plurality of drive strength values representing a first level of power consumption in the transmit circuit (201); determining whether the first level of power consumption exceeds a maximum level of power consumption in the transmit circuit (201); and reducing a predetermined one of the plurality of drive strength values if the first level of power consumption exceeds the maximum level of power consumption.
