ABSTRACT:
An example embodiment is directed to an arrangement and method for phase-aligning digital data to be sent by transmit-data modules over respectively-situated serial links. A reference clock signal is communicatively coupled to each transmit-data module, each transmit-data module having a data driver and a clock circuit. At the serial links, each respective data driver sends digital data in response to a clock-output signal and a phase-adjusted clock-load signal that is used to load the data driver. The phase of the clock-load signal is adjusted relative to misalignment between the clock-load signal and the reference clock signal so that each data driver loads the digital data in a time-aligned manner for link transmission. The present invention is useful in applications involving programmable logic devices and other skew-susceptible parallel transmission arrangements.
