Developed by Inova Semiconductors, APIX (Automotive Pixel Link) is a multi-channel technology for high-resolution in-vehicle video applications. The new APIX3 version supports transmission speeds of up to 6 Gbps over a single twisted-pair (STP) cable and up to 12 Gbps over a quad-twisted-pair (QTP) connection, which is four times the speed of the previous APIX2 generation. This means that APIX3 supports HD and Ultra HD video displays.
By supporting different wired communication media – STP, QTP, and coaxial – APIX3 reduces cable costs for car manufacturers, original equipment manufacturers, and Tier 1 suppliers. It provides scalable bandwidth, meaning it can be used from entry-level to high-end systems.
APIX3 offers a number of features not available in alternative automotive video technologies. First, it allows the transmission of multiple video channels over a single connection, thus supporting advanced vehicle architectures. It also supports 100 Mbit Ethernet and other popular serial interface protocols. Finally, APIX3 provides advanced diagnostic capabilities, including cable monitoring for proactive detection of cable degradation.
“Building on Inova’s experience with the 30 million APIX devices already deployed in vehicles, APIX3 offers the bandwidth and features needed for the latest generation of in-car video applications,” said Thomas Rothhaupt, Director of Sales and Marketing at Inova Semiconductors. “As manufacturers add more and more video to their vehicles, including multiple cameras and connected devices, APIX3 offers a flexible, reliable, and cost-effective solution.”
The first products based on Inova APIX3 are already under development, with samples available for key customers. General sample shipments will begin in Q3 2016. An APIX3 test chip is currently available from Inova for evaluation.
The APIX3 IP is now available for licensing. The first license agreement is being negotiated and is expected to close before the end of 2015. Inova is also working with its partners to establish a complete support ecosystem, including cables and connectors.
The new APIX3 technology is backward compatible with APIX2. It provides full-duplex communication channels and an active equalizer to automatically adjust to individual transmission lines, enabling plug-and-play connectivity. It also provides compensation for cable aging and temperature. APIX3 supports relevant safety applications (ISO26262) and meets automotive industry EMI and robustness requirements.
