Automotive HD link complements auto safety systems
Automation / Robotics
RENESAS ELECTRONICS Automotive HD Link (AHL) technology enables automotive manufacturers to deliver high-definition video over low-cost cables and connectors that currently support standard-definition video. AHL can be paired with firm’s other products, such as the R-Car Automotive SoCs, RH850 MCUs, automotive PMICs, and analog components to cost-effectively implement numerous safety features in virtually any vehicle.
RAA279971 AHL encoder and RAA279972 decoder use a modulated analog signal to transmit the video, enabling transmission rates 10 times less than required to transmit HD signals digitally. The lower transmission rate means that traditional twisted pair cables and standard connectors can be used, as can existing analog video cables and connectors. On the other hand, digital links such as SerDes require heavily shielded cables and high-end connectors that cost significantly more than those for AHL, may require replacement after 5-7 years and are difficult to route due to bending radius limitations.
