Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Renesas Electronics, a global semiconductor solutions provider, today announced the launch of the RAA278830 video diagnostic bridge IC. As a highly integrated dual-channel low-voltage differential signal (LVDS) LCD video processor, the new IC integrates several core functions required for ISO 26262 ASIL Class B in-vehicle display systems. It is suitable for key application scenarios such as head-up display system (HUD), digital dashboard, electronic rearview mirror (CMS) and streaming media rearview mirror.

As automotive safety systems increasingly rely on display systems, presenting clear, error-free images to drivers becomes critical. Lost frames, frozen images and even wrong warning ICONS can seriously endanger driving safety. The RAA278830 has built-in functional safety features that prevent any image damage by monitoring signal integrity and the video content itself. Its internal diagnostic and measurement engine detects frozen video, abnormal colors, broken or damaged images, as well as blinking, shaking, and images that may obscure the driver's view of the road (for the HUD system).

Renesas expertise in in-vehicle video signal processing

Renesas has long been committed to providing superior video signal processing solutions for the automotive electronics application market. In addition to the standard analog video decoder, Renesas also introduces the award-winning Automotive HD-Link (AHL) family of products that support the transmission of high-resolution images over low-cost cables and connectors. The release of the RAA278830 further expands Renesas' already widely used line of integrated LCD controllers.
