Claim Text:
1. A reflection cancellation apparatus comprising: a predriver including a plurality of elements, each of the plurality of elements to receive one of a plurality of clock signals and to provide a data sample delayed by a time determined by the respective clock signal; a plurality of circuit units each coupled to receive a data signal sample from a respective one of the plurality of elements of the predriver, and each of the plurality of circuit units coupled at an output node to output an output signal to an communication channel; and a time adjustment unit to generate the plurality of clock signals and to adjust timing of the plurality of clock signals to at least partially cancels noise in the output signal caused by a signal reflection from the communication channel, wherein the plurality of clock signals have phase differences that respectively correspond to different multiples of an expected time of flight across the communication channel.
