Abstract
In a receiver circuit, a node receives a signal that carries data from a transmitter circuit. Moreover, a clock-data-recovery (CDR) circuit in the receiver circuit recovers an at-rate clock signal from the received signal. The CDR circuit recovers the clock signal without converging a first pulse-response precursor of the signal relative to a pulse-response cursor of the signal to approximately zero (e.g., with the first pulse-response precursor h(−1) converged to a non-zero value). Furthermore, the first pulse-response precursor corresponds to at least one precurosor or postcursor of the pulse-response other than the current sample.
