Abstract
A method for digital timing recovery from oversampled analog signals includes computing filter coefficients for digitized samples of the oversampled analog signals based on an oversampling factor of the oversampled analog signals, using the filter coefficients in a rotation filter to compensate for the oversampling factor in the digitized samples of the oversampled analog signals, deriving a starting phase and magnitude from the compensated digitized samples of the oversampled analog signals, and using the starting phase and magnitude in a timing recovery loop to recover a clock from the compensated digitized samples of the oversampled analog signals. The rotation filter may include a plurality of taps, and the circuitry may be configured to compute respective sets of coefficients for respective taps. Each set of coefficients may be dependent on another set of coefficients, or the coefficients may be approximate with each set of approximate coefficients being independent.
