Abstract
Methods and systems are provided for training an analog-to-digital converter (ADC) of a receiver. The methods and systems access a training sequence comprising a plurality of unscrambled portions interleaved with a plurality of scrambled portions and destabilize a clock data recovery (CDR) component to generate a random frequency offset. The methods and systems instruct an ADC to sample the training sequence, using a set of clock signals generated by the phase interpolator (PI) using the CDR component based on the random frequency offset, to generate a set of digital symbols representing the plurality of unscrambled portions and the plurality of scrambled portions. The methods and systems calibrate an ADC offset based on the training sequence that has been sampled by the ADC using the set of clock signals generated by the PI using the CDR component based on the random frequency offset.
