Abstract
A receiver may sample an amplitude-modulated input signal expressed as a series of symbols using a clock signal with edges aligned to the symbols. Repeated symbols and the level transitions between them may form signal eyes. The receiver may detect the inner signal eyes and aligns the phase of the clock signal relative to the symbols responsive to the detected timing center of signal eyes and corresponding symbol patterns.
