Method and apparatus for synchronizing a multiple-stage multiplexer |
摘要 |
A method and apparatus for synchronizing multiple-stage multiplexers are disclosed. According to exemplary embodiments of the present invention, multiplexer circuits in the multiple-stage multiplexer are synchronized based upon a frequency response of the output of the multiplexer. The power level of the output of the multiple-stage multiplexer is measured at a frequency corresponding to the input data rate of the multiple-stage multiplexer, during the time a test pattern is sent through the multiple-stage multiplexer. In an exemplary embodiment of the invention, the multiple-stage multiplexer is placed in substantially random states until the measured power level reaches the predetermined.
