Claim One:
1. A multi-lane analog to digital converter (ADC) for converting an analog input from an analog signal domain to a digital signal domain to provide digital output samples, comprising: a plurality of ADCs configured to convert the analog input from the analog signal domain to the digital signal domain to provide a plurality of digital output segments, the plurality of ADCs being configured to sample the analog input using a corresponding phase from among multiple phases of a sampling clock, the multiple phases being offset from each other; a switching module configured to interleave the plurality of digital output segments to provide the digital output samples; and an impairment detection module configured to generate a calibration signal having a known characteristic, and determine statistical relationships between the plurality of digital output segments and the calibration signal to quantify impairments induced by the plurality of ADCs on the plurality of output segments.
