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 first plurality of digital output segments in a first mode of operation, each of 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, and convert a calibration signal from the analog signal domain to the digital signal domain to provide a second plurality of digital output segments in a second mode of operation, each of the plurality of ADCs being configured to sample the calibration signal using the corresponding phase from among the multiple phases of the sampling clock; a switching module configured to interleave the first plurality of digital output segments to provide the digital output samples; and an impairment detection module configured to: generate the calibration signal having a known characteristic in the second mode of operation, and determine statistical relationships between the second plurality of digital output segments and the calibration signal to quantify impairments induced by the plurality of ADCs on the first plurality of digital output segments.
