Abstract
Aspects of the disclosure pertain to an apparatus for detecting timing errors including an analog to digital converter circuit, a diversity loop detector and a timing error calculation circuit. The analog to digital converter circuit is operable to convert an input signal into a series of digital samples. The diversity loop detector is operable to apply a data detection algorithm to a plurality of signals derived from the series of digital samples at different phase offsets, to select one of the phase offsets, and to yield a detected output with the selected phase offset. The timing error calculation circuit is operable to calculate a timing error of the analog to digital converter circuit based at least in part on the selected phase offset.
