System and method for calibration of serial links using a serial-to-parallel loopback

摘要

A system and method for calibration of serial links using serial-to-parallel loopback. Embodiments of the present invention are operable for calibrating serial links using parallel links thereby reducing the number of links that need calibration. The method includes sending serialized data over a serial interface and receiving parallel data via a parallel interface. The serialized data is looped back via the parallel interface. The method further includes comparing the parallel data and the serialized data for a match thereof and calibrating the serial interface by adjusting the sending of the serialized data until the comparing detects the match. The adjusting of the sending is operable to calibrate the sending of the serialized data over the serial interface.

1. A method for calibrating communication, said method comprising:
sending serialized data over a serial interface from a first location; receiving parallel data via a parallel interface from a second location, wherein said parallel data comprises a deserialized representation of said serialized data, wherein said parallel data is looped back to said first location via said parallel interface; comparing said parallel data received from said second location and said serialized data sent from said first location for a match thereof; and calibrating said serial interface by adjusting said sending of said serialized data until said comparing detects said match.
