Abstract:
1. A system comprising: a fast phase alignment component configured to generate a selected phase signal based on an edge of an incoming signal, wherein the selected phase signal includes at least an approximation of a phase of an edge of the incoming signal; a signal detector configured to detect, the incoming signal and activate the fast phase alignment component in response to detecting the incoming signal, wherein activating the fast phase alignment component comprises switching the fast phase alignment, component from a deactivated or off state to an activated or on state; a clock and data recovery component configured to receive the selected phase signal and perform a clock and data recovery function on the incoming signal using the selected phase signal; and at least one sampler configured to receive the incoming signal and one or more phase adjusted clock signals; wherein the sampler is configured to sample the incoming signal based on rising and falling edges of a first phase adjusted clock signal, to sample the incoming signal based on rising and falling edges of a second phase adjusted clock signal, and to sample the incoming signal based on rising and falling edges of a third phase adjusted clock signal, wherein the second phase adjusted clock signal has a different phase than the first phase adjusted clock signal, wherein the third phase adjusted clock signal has a different phase than the first phase adjusted clock signal or the second phase adjusted clock signal, and wherein the difference between the phases of the first phase adjusted clock signal and the second phase adjusted clock signal is larger than the difference between the phases of the second phase adjusted clock signal and the third phase adjusted clock signal.
