Twin SerDes devices for simultaneous transmission of video, audio and data
Two new APIX3 SerDes twin transmitters, each with two independent transmission channels, are now available from Inova Semiconductors. APIX (Automotive Pixel Link) is a multi-channel SerDes (serializer/deserializer) technology developed by Inova for high-resolution video applications in motor vehicles.

Typical applications for the new APIX3 chips are infotainment and entertainment systems, as well as instrument clusters and head-up displays in vehicles. The latest APIX3 generation can host multiple display connections with bandwidths of up to 12 Gbps and supports HD and Ultra HD displays.

The latest additions to the APIX3 family are the INAP562TAQ transmitters with HDMI 1.4a (with 3D support) and DSI 1.2 video interface and the INAP564TAQ with two DSI 1.2 video interfaces. Both transmitters differ only in terms of the video inputs and are otherwise compatible. Each of these transmitters can provide two APIX3 links via STP or coaxial cable with the INAP562R receiver already available. This means that one transmitter can control two receivers with completely independent image and data content, which previously required two transmitter devices. This results in reduced system costs and a smaller space requirement on the transmitter-side control unit. The devices support various EMC-friendly operating modes with fixed bandwidths of 1.5; 3 or 6 Gbps in single-lane mode, with a fixed back channel of 187.5 Mbps. The new chips of the APIX3 family are designed for popular displays (e.g. 2880 x 1080 x 24 bit, 60 Hz) in cars.
