Overview
Description
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 or a DVP/BT.656 parallel interface. The RAA279972 has integrated short-to-battery and short-to-ground detection and image enhancement feature, 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.
