Abstract
Determining a phase error in a data signal includes detecting bits in an original data signal, determining a phase error in the original data signal based on the detected bits, adjusting a clock signal based on the phase error, sampling the original data signal with the clock signal to produce a sampled data signal, and repeating detecting, determining, adjusting and sampling using the sampled data signal instead of the original data signal.
