20100322367 | Fast Phase Alignment for Clock and Data Recovery - Disclosed herein are systems and methods for fast phase alignment and clock and data recovery. Systems and methods may include a fast phase alignment component configured to generate a selected phase signal based on a characteristic of an incoming signal. A clock and data recovery component may also be configured to receive the selected phase signal and perform a clock and data recovery function on the incoming signal using the selected phase signal. | 12-23-2010 |
20130003907 | ENHANCED PHASE DISCRIMINATOR FOR FAST PHASE ALIGNMENT - One embodiment of the present invention relates to a phase alignment system including a plurality of samplers, a clock distributor, a phase detector and a phase alignment control. The samplers are configured to receive an incoming signal and a phase adjusted clock signal and to provide samples according to the incoming signal. The clock distributor receives a clock adjustment signal and generates the phase adjusted clock signal, which triggers sampling of the incoming signal. The clock adjustment signal indicates a direction of phase adjustment and can include an amount of phase adjustment. The phase detector receives the samples and provides extended phase alignment commands derived from the samples. The phase alignment control receives the extended phase alignment commands and provides the clock adjustment signal to the clock distributor. | 01-03-2013 |
