In-car video link at 12Gbps for high resolution

October 16, 2015 // By Graham Prophet
Inova Semiconductors has announced its APIX3 multi-channel SerDes (serialiser/deserialiser) technology for video and data communication in vehicles. It aims to enable a 4x speed-up in video transmission for efficient, cost-effective next-generation automotive infotainment

Inova Semiconductors’ (Munich, Germany) APIX (Automotive Pixel Link) is a multi-channel technology for high resolution in-car video applications. The latest APIX3 version supports transmission at 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 video with HD and Ultra HD displays.

By supporting different cable media – STP, QTP and co-axial – APIX3 reduces the cost of cables to automotive manufacturers, OEMs and tier 1 suppliers. It provides scalable bandwidth, which means it can be used from entry level to high end systems.

APIX3 provides a number of features that Inova asserts are not available with alternative technologies for in-car video. Firstly, it enables the transmission of multiple video channels on one connection, supporting advanced cockpit architectures. It also supports 100 Mbit Ethernet and other serial interface protocols. Finally, APIX3 provides advanced diagnostic capabilities, including cable monitoring for preventive detection of cable degradation.

“Building on Inova’s experience with the 30 million APIX devices deployed in cars already, APIX3 provides the bandwidth and features required for the latest generation of automotive video applications,” said Thomas Rothhaupt, Director Sales & Marketing at Inova Semiconductors. “As manufacturers are adding more and more video to their cars, including multiple cameras and connected devices, APIX3 provides a flexible, reliable and cost-effective solution.”

The first Inova products based on APIX3 are now in development and sampling to key customers, with general sampling due in Q3 2016. An APIX3 test chip is available today for evaluation from Inova.

The APIX3 IP is available now for licensing, with the first licensing deal being negotiated and expected to be closed before the end of 2015. Inova is also working with its partners to establish a full supporting ecosystem, including cables and connectors.

APIX3 technology is backward compatible with APIX2.
