摘要: The invention discloses a data synchronous transmission device based on spread spectrum technology. comprises clock generation module, pre-synchronization circuit and synchronization processing circuit. spread-spectrum module receives an input signal generates output signal; pre-synchronizing the data, latches reverse edge of signal, sends to after receiving writes in according timing sequence then shifts out signal. can synchronously keeps normal, cannot cause problem that are asynchronous, significantly reduces system EMI interference since frequency superimposed with low for modulation.
