The RAA279972 is a high-definition analog video

decoder designed for automotive applications. It

supports single-ended, differential, and

pseudo-differential analog composite high-definition

AHL video inputs. The high-quality 10-bit video ADC

converts the signal to digital, and a proprietary AHL

adaptive comb filter separates Luma and Chroma

data to output a YUV422 digital video signal over a

two-lane MIPI-CSI2 interface, DVP, or a BT.656

parallel interface. The RAA279972 has integrated

short-to-battery and short-to-ground detection and

image enhancement features, making it an ideal

solution for demanding high-resolution automotive

camera applications. When paired with the

RAA279971 encoder, an analog video link is

established over a single wire pair.

1. Descriptions of circuits, software and other related information in this document are provided only to illustrate the operation of semiconductor products

and application examples. You are fully responsible for the incorporation or any other use of the circuits, software, and information in the design of your

product or system. Renesas Electronics disclaims any and all liability for any losses and damages incurred by you or third parties arising from the use of

these circuits, software, or information.

2. Renesas Electronics hereby expressly disclaims any warranties against and liability for infringement or any other claims involving patents, copyrights, or

other intellectual property rights of third parties, by or arising from the use of Renesas Electronics products or technical information described in this

document, including but not limited to, the product data, drawings, charts, programs, algorithms, and application examples.

3. No license, express, implied or otherwise, is granted hereby under any patents, copyrights or other intellectual property rights of Renesas Electronics or

others.

4. You shall be responsible for determining what licenses are required from any third parties, and obtaining such licenses for the lawful import, export,

manufacture, sales, utilization, distribution or other disposal of any products incorporating Renesas Electronics products, if required.

5. You shall not alter, modify, copy, or reverse engineer any Renesas Electronics product, whether in whole or in part. Renesas Electronics disclaims any

and all liability for any losses or damages incurred by you or third parties arising from such alteration, modification, copying or reverse engineering.

6. Renesas Electronics products are classified according to the following two quality grades: “Standard” and “High Quality”. The intended applications for

each Renesas Electronics product depends on the product’s quality grade, as indicated below.

"Standard": Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home

electronic appliances; machine tools; personal electronic equipment; industrial robots; etc.

"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control (traffic lights); large-scale communication equipment; key

financial terminal systems; safety control equipment; etc.

Unless expressly designated as a high reliability product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas

Electronics document, Renesas Electronics products are not intended or authorized for use in products or systems that may pose a direct threat to

human life or bodily injury (artificial life support devices or systems; surgical implantations; etc.), or may cause serious property damage (space system;

undersea repeaters; nuclear power control systems; aircraft control systems; key plant systems; military equipment; etc.). Renesas Electronics disclaims

any and all liability for any damages or losses incurred by you or any third parties arising from the use of any Renesas Electronics product that is

inconsistent with any Renesas Electronics data sheet, user’s manual or other Renesas Electronics document.

7. No semiconductor product is absolutely secure. Notwithstanding any security measures or features that may be implemented in Renesas Electronics

hardware or software products, Renesas Electronics shall have absolutely no liability arising out of any vulnerability or security breach, including but not

limited to any unauthorized access to or use of a Renesas Electronics product or a system that uses a Renesas Electronics product. RENESAS

ELECTRONICS DOES NOT WARRANT OR GUARANTEE THAT RENESAS ELECTRONICS PRODUCTS, OR ANY SYSTEMS CREATED USING

RENESAS ELECTRONICS PRODUCTS WILL BE INVULNERABLE OR FREE FROM CORRUPTION, ATTACK, VIRUSES, INTERFERENCE,

HACKING, DATA LOSS OR THEFT, OR OTHER SECURITY INTRUSION (“Vulnerability Issues”). RENESAS ELECTRONICS DISCLAIMS ANY AND
