Overview
Description
The RAA278842 and RAA278843 are highly integrated LCD video processors that incorporate many of the features required to create a cost effective multipurpose LCD display system. These include a high quality 2D comb NTSC/PAL/SECAM video decoder that supports single-ended or differential composite video inputs, two TTL digital input interfaces, two LVDS Open LDI input interfaces, a MIPI-CSI2 input interface, and an EEPROM/SPI interface. The outputs include a dual channel LVDS Open LDI panel interface and a separate MIPI-CSI2 output in the RAA278842 or a pseudo BT. 656 output in the RAA278843.
Both devices can support input resolutions up to 1080p and can drive LCD panels up to 1920x1080. The video processing capabilities include arbitrary H/V scaling using a high quality scaler and de-interlacer engine, panoramic scaling, image mirroring, image adjustment and enhancement using 10-bit per color processing, black and white stretch, a versatile OSD, and much more. In addition, the RAA278842 and RAA278843 have a multi-feature image integrity diagnostic capability to dynamically determine if the input video is corrupted. The feature set and versatility of this device makes it an ideal solution for automotive LCD display applications.

Decoupling capacitors on power lines of RAA278842
Hello Renesas, In the datasheet of RAA278842 video processor there is no recommendation for using decoupling capacitors on powerlines. Is it really not required any decoupling capacitors on this power lines, if yes why , if required what value of decoupling capacitor to be connected ?

RAA278842 flash question
Hi sir, we plan to use RAA278842 to implement automotive rear seat display. now we need some information about the flash size. If we want to use SPI-OSD, and maybe register initialize data, do you have any suggestion flash size to do it ? Thanks Jack
