ABSTRACT:
A timing recovery circuit for a receiver may include a timing error detector that generates a timing error based on differences between coefficients of a feed-forward filter and a feed-back filter. The timing recovery circuit may include a loop filter which generates a control voltage signal based on the timing error, and a voltage controlled oscillator that generates a sampling clock for the receiver based on the generated control voltage signal.
