Dynamically calibrating the offset of a receiver with a decision feedback equalizer (DFE) while performing data transport operations

摘要

Dynamically calibrating an offset of a receiver with a DFE while performing data transport operations, the DFE comprising a plurality of independent data transport banks, at least one data transport bank operating a data transport mode and at least one data transport bank operating in a calibration mode, including: iteratively, while carrying out data transport operations: utilizing the data transport bank operating in the data transport mode to perform data transport operations; calibrating the data transport bank operating in the calibration mode; and upon completing calibration of the data transport bank operating in the calibration mode, switching the mode of each data transport bank.

1. A method of dynamically calibrating an offset of a receiver with a Decision Feedback Equalizer (‘DFE’) while performing data transport operations, the DFE comprising a plurality of independent data transport banks, at least one data transport bank operating a data transport mode and at least one data transport bank operating in a calibration mode, the method comprising:
iteratively, while carrying out data transport operations:
utilizing the data transport bank operating in the data transport mode to perform data transport operations;calibrating the data transport bank operating in the calibration mode; andswitching the mode of each data transport bank upon completing calibration of the data transport bank operating in the calibration mode, wherein switching the mode of each data transport bank comprises switching the mode of the data transport bank operating in the calibration mode to the data transport mode and switching the mode of the data transport bank operating in the data transport mode to the calibration mode.
