Infotainment link quadruples bandwidth

October 15, 2015 // By Christoph Hammerschmidt
Inova Semiconductors has introduced a new iteration of its APIX in-car infotainment connectivity technology. APIX 3 supports data rates up to 6 Gbps with STP and coax wiring and up to 12 Gpbs over a quad twisted pair (QTP) connection, enabling playback of video content with HD and UHD resolution on rear-seat screens.

The APIX 3 chip offers a number of features not available with competing technologies: It supports multiple video streams over a single channel and thus supports the latest infotainment and car cockpit architectures. In addition, it supports 100 Mbit/s Ethernet and other widespread interface protocols. Last but not least APIX 3 offers diagnosis functions including channel monitoring that enables it to detect flagging cable quality at an early phase.

“Carmakers increasingly integrate video technology into their vehicles, such as multiple cameras and displays,” says Inova Semiconductor sales director Thomas Rothaupt. “For such environments, APIX 3 offers a reliable and cost-effective solution”.

Currently, first chips are being sampled at selected large customers. General sampling will start in Q3 2016, but test chips are available now, the company said. Likewise, the IP is available for third-party licensing. The Munich-based chipmaker is currently developing a comprehensive support ecosystem with partners.

APIX 3 is backward-compatible to its predecessor chip APIX 2. It supports full duplex data connections and an active equaliser for the automated individual alignment to the respective transmission line which enables plug-and-play connectivity. It meets the requirements of functional safety according to ISO 26262 as well as the automotive-specific electromagnetic immunity.
