A clock data recovery (CDR) apparatus can include an interpolator circuitry to interpolate an input received signal and to generate an output signal removing the sampling clock offsets. The apparatus can include timing error detector (TED) circuitry coupled to process the output signal and to provide a timing error as feedback to the interpolator circuitry, the timing error being adjusted by gain factors used in at least one of an automatic gain control (AGC) circuitry and an orthogonalization circuitry. The apparatus can include loop filter (LF) circuitry to filter the timing error to remove noise effects. The apparatus can include numerically controlled oscillator (NCO) circuitry to adjust for a basepoint and fractional interval used to adjust resampling coefficients within the interpolator circuitry.
