Abstract
In a digital data receiver, it is desirable to use the equalized data for deriving time synchronization information. This invention minimizes timing contention between an equalizer operating at a T/2 rate and a timing recovery circuit which utilizes the output of the equalizer. An interpolator interpolates T1 and T2 data samples from the equalizer and provides data signals R and S equally spaced relative to the peak baud amplitude which can be easily processed by the timing recovery circuit.
