ADAS deserialiser integrates four surround view camera streams

July 28, 2015 // By Graham Prophet
The MAX9286 quad deserialiser enables the design of surround-view systems for ADAS (advanced driver assistance systems) with fewer components and faster design-time. One MAX9286 gigabit multimedia serial link (GMSL) deserialiser receives and automatically synchronizes video from up to four cameras.

Surround view systems are a key component in today’s ADAS market. Maxim’s MAX9286 automotive deserialiser accepts and synchronises video streams from four cameras via a shielded twisted-pair (STP) or coaxial cable by up to 15 metres. The MAX9286 outputs the data via a four-lane, industry-standard CSI-2 interface to a video processor. It reduces board space and component count by replacing four discrete deserialisers and an FPGA. This highly integrated deserializer eliminates additional software required for camera synchronisation. The MAX9286 is also suited for machine vision and 3D-camera systems.

The part, Maxim adds;

- shortens design time, lowering design risk and time to market with automatic generation of camera synchronisation signals, alignment of image data from multiple sensors to the same pixel, and user programmability of key parameters.

- lowers cost: integration reduces board space and component count by eliminating four discrete deserialisers and an FPGA. It also supports power over coaxial cabling to reduce wiring and cost.

- adds diagnostic capability, enhancing system integrity with on-chip diagnostics for link bit error rate (BER), detection of camera falling out of sync, or cable shorts to power/ground.

In 56-pin, 8 x 8 mm TQFN and QFND packages, the device is specified over the -40 to +105C range; AEC-Q100 qualified parts are available, and there is an evaluation kit with SoC processor available. ADAS-specific reference designs developed with ecosystem partners also available.
