Abstract: A method for setting a link and detecting a failure by using an LVDS SERDES is provided to check PLL(Phase Locked Loop) lock of serializers of both ends of an initial link, initialize the link to a data transceiving state, and detect a link failure in the link using the LVDS SERDES by checking signal integrity without changing a test mode while transceiving frame data having a finite length. If link setting is started, a sync pattern transmitting state is kept for 100ms by controlling the SERDES after setting a link setting failure state as a current state(810). It is checked whether a PLL is locked or not by checking a state of the SERDES after 100ms(890). If abnormality is checked, checkup is repeated after keeping the sync pattern transmitting state for 10ms. If the PLL is locked, a loop back test count is initialized, the count is increased after continuously transmitting the same loop back pattern for 150 words, and it is checked whether all loop back patterns are returned(850). If all loop back pattern is returned, the link setting state is set as a success state(860).
