ABSTRACT:
The invention relates to an interpolation module, an interpolator, and methods capable of recovering timing, and in particular, to an interpolation module, an interpolator, and methods capable of recovering timing in a timing recovery apparatus. An interpolation module capable of recovering timing in a timing recovery apparatus comprises a first symbol inverse unit for shifting phase of a digital input signal by 180 degrees to generate a first inverted signal comprising a plurality of sampling values; an interpolator coupled to the first symbol inverse unit for interpolating the plurality of sampling values according to a fractional interval to generate an interpolated signal, which comprises a plurality of interpolants; and a second symbol inverse unit coupled to the interpolator for shifting phase of the interpolated signal by 180 degrees to output a second inverted signal.
