The RAA278842 LCD video controller’s 4-lane (or dual 2-lane) MIPI-CSI2 input supports up to 1 Gbps per lane to interface with the latest generation of automotive cameras, application processors and graphics processors. The controller also supports a 150 MHz single-channel OpenLDI interface, and a variety of video interfaces and LCD panel sizes with resolutions up to 1920x1080. The RAA278842 is well suited for automotive central infotainment displays (CIDs) and head units, instrument clusters, head-up displays (HUDs), and mirror replacement display applications that are essential for the growing needs of advanced driver assistance systems (ADAS).
The chip has 10-bit per colour processing built into the image enhancement engine to provide near-zero latency, high quality video. Its integrated video diagnostics detects if the incoming video is frozen or corrupted and can provide a direct path for the rear camera video to be displayed on the LCD. This significantly improves rear camera display reliability, virtually eliminating the possibility of a software related problem causing the rear camera video to be displayed incorrectly or not at all. And because some application processors take several seconds to boot up (depending on the OS), the RAA278842 can display the camera image on an LCD in less than 500 milliseconds, thereby addressing the fast boot requirement of many OEMs.
