MIPI DSI-RX Data 4-lane, CLK 1-lane with data rates up to 800 Mbps/lane.
Video frame size:
Up to 1600x1200 24-bit/pixel resolution for single-link LVDS display panel
limited by 135 MHz LVDS speed
Up to WUXGA (1920x1200 24-bit pixels) resolution for dual-link LVDS display
panel, limited by 270 MHz LVDS speed.
