Abstract:
A method of measuring signal impairments is disclosed for use in an asynchronous Digital Signal Processing (DSP) based data and timing recovery circuit including an interpolator circuit. The method includes: calculating amplitude values for data and timing recovery; calculating an interpolation index for the interpolator circuit; and overriding the interpolation index. In another implementation, a method of measuring signal impairments in an asynchronous DSP-based data and timing recovery circuit including an interpolator circuit includes: calculating amplitude values for data and timing recovery; calculating a timing control signal; and overriding the timing control signal.
