LVDS

The conga-MEVAL provides LVDS connectors CN6 and X65. Connector CN6 supplies 3.3 V or 5 V LVDS panel power. The power/backlight
connector X35 supplies 5 V or 12 V backlight power (maximum output current of 1 A) to CN6 and X65, as well as 3.3 V or 5 V panel power to X65.
Use jumper X33 to select the LVDS panel power and jumper X34 to select the LVDS backlight power. For LVDS functionality on CN6 or X65,
set jumper X87 to position 2-3.
