6.3 Signal Description
The module using one LVDS receiver SN75LVDS82(Texas Instruments). LVDS is a
differential signal technology for LCD interface and high speed data transfer device. LVDS
transmitters shall be SN75LVDS83(negative edge sampling). The first LVDS port(RxOxxx)
transmits odd pixels while the second LVDS port(RxExxx) transmits even pixels.
