Twin APIX3 SerDes chips enable high-end infotainment in the car
Inova Semiconductors has developed two new SerDes modules for applications in the vehicle interior in connection with the APIX3 data bus (Automotive Pixel Link). The chips have two independent communication channels with data rates of up to 6 Gbps per channel. Typical applications for the chips are infotainment and entertainment systems as well as instrument clusters and head-up displays in vehicles.

The devices enable the simultaneous transmission of up to eight audio channels. A special feature of the APIX technology is the media-independent interface (MII, RMII, RGMII) for 100 Mbit Ethernet according to the IEEE standard. An SPI interface for convenient configuration of the components and data transmission is also available.

The APIX3 components are backwards compatible with the APIX2 predecessor family and, like these, offer compensation functions for cable aging and temperature fluctuations. New with APIX3 is the automatic calibration (link training) of the APIX3 link to the used cable medium. This results in a very robust, stable and optimized transmission. With its many diagnostic functions, APIX3 supports safety-relevant applications and meets the requirements of the automotive industry with regard to electromagnetic immunity and resistance.

The two new APIX3 transmitters are available now. The devices are qualified according to AEC-Q100, operate in a wide temperature range from -40 °C to +105 °C and are supplied in a 151-pin aQFN package. They are pin compatible with the available single channel APIX3 transmitters INAP563TAQ and INAP565TAQ. The components are also available as variants with HDCP (High-bandwidth Digital Content Protection). The APIX3 technology was also licensed by Inova to Socionext.
