Function
LVDS Differential Clock for LVDS_C Input Port (LVDS_CLKC+, LVDS_CLKC).
In LVDS input mode, INA[0 :15] and INB[0 :15] form a differential pair
LVDS_A+[0:15] (positive node) and LVDS_A–[0:15] (negative node), respectively.
In LVDS input mode, INC[0 :15] and IND[0 :15] form a differential pair
LVDS_C+[0:15] (positive node) and LVDS_C–[0:15] (negative node), respectively.
