Abstract:
1. A method of de-skewing a plurality of serial data signals respectively outputted from a plurality of data lanes, the method comprising: providing a de-skew signal for initiating a de-skewing process; simultaneously feeding a test signal to inputs of the plurality of data lanes and monitoring respective outputs thereof; respectively detecting a predetermined data element of the test signal outputted from each of the plurality of data lanes; measuring respective elapsed times from the detection of the predetermined data element outputted from each of the plurality of data lanes to the detection that the predetermined data element has been outputted from all of the plurality of data lanes; and de-skewing the plurality of serial data signals by respectively delaying them in accordance with their respective measured elapsed times; wherein, once de-skewed, further determination of elapsed times occurs only when another de-skew signal is received.
