Abstract
An equalizer is disclosed, and associated operational method. The equalizer has a configuration that balances performance and complexity by obtaining samples that are strongly correlated with future and past transmitted bits, and are weakly correlated with future and past bit transitions, and is useful for timing recovery circuits. Samples are only obtained or collected at time intervals more than one sample period away from the reference sample. Samples are shifted by a delay value less than the sample period, and are obtained at a sample period of one unit interval. A means to adjust the sampling point delay is also disclosed. In an implementation, samples that are within the sample period away from the reference sample are obtained and used for implementing a timing shift, not for equalization of the timing recovery signal. Embodiments are also disclosed for optimizing performance for data recovery.
