CONTINUOUS ADAPTIVE DATA CAPTURE OPTIMIZATION FOR INTERFACE CIRCUITS

Номер: US20160006423A1
Автор: IYER Venkat, LEE Jung, Murdock Brett
Принадлежит:

A continuously adaptive timing calibration function for a data interface is disclosed. A first calibration method is performed for a mission data path, typically at power-on, to establish an optimal sample point. Reference data paths are established for a second calibration method that does not disturb normal system operation. Data bit edge transitions are examined at fringe timing points on either side of the optimal sample point. Assuming that a timing change for the edge transitions indicates a drift of the optimal sample point, when a drift amount is determined to be greater than a correction threshold value the optimal sampling point for the mission path is adjusted accordingly. At no point does the continuous calibration function determine that any data bit is invalid since the optimal sampling point is always maintained. Also, at no point does continuous calibration require successive alternating data bit values such as 1-0-1 or 0-1-0. 1. A method for operating a data interface circuit whereby calibration adjustments for data bit capture are made without disturbing normal system operation , comprising;receiving a first stream of data bits input to the data interface circuit;initially establishing, using a first calibration method, an optimal sampling point for sampling the data bits input to the data interface circuit;receiving a second stream of data bits input to the data interface circuit during normal system operation; establishing at least one reference data path for sampling transition edges of the second stream of data bits input to the data interface during normal system operation;', 'using the at least one reference data path, sampling a plurality of fringe timing points associated with transition edges of the second stream of data bits input to the data interface circuit;', 'comparing a first fringe timing measurement made during a first performance of the second calibration method, with a second fringe timing measurement made during a second ...
