Automotive High Definition Link Encoder Evaluation Board
The Automotive High Definition Link (AHL) platform comes with two evaluation boards (EVB). One is an AHL transmitter with integrated AHL encoder (RAA279971), HDMI input...
Overview
Description
The RAA279971 is a high-definition analog video encoder that is designed for automotive applications. It accepts digital video input using a 2-lane MIPI-CSI2 or a DVP/Pseudo BT.656 parallel interface and supports multiple high-definition resolutions up to 720p/60 or 1080p/30. The RAA279971 uses a built-in 10-bit video DAC that encodes the incoming video stream into an analog composite format that is transmitted to an RAA279972 decoder as a single-ended or differential signal over up to 30 meters of either coax or STP cable.
