Honored ContributorWhat device and interface speed? Are you doing Dynamic-Phase Alignment(DPA)?
Most LVDS interfaces "close timing", i.e. the parallel bus is all captured correctly and synchronously. Only at the really high speeds with DPA on might each lane align indpendently, in which case you need to align the lanes. Assuming you are closing timing, the sync is generally used to do word alignment, i.e. the data coming out is supposed to be D7_D6...D0, but might be something like D2_D1_D0_D7_D6...D3(where the D2-D0 is an adjacent word to D7-D3). If the sync is supposed to output a specific pattern, then just shift all the channels until sync has that patter, and the data channels will also be word aligned.
